No. It's not true that babies are born with the ability to swim, though they have reflexes that make it look like they are.

A reflex called the bradycardic response makes babies hold their breath and open their eyes when submerged in water, says Jeffrey Wagener, a pediatric pulmonologist in Colorado. (Parents can cause this same reaction by blowing in their baby's face, a response that disappears after about 6 months.

Also, until around 6 months, babies placed in water tummy down reflexively move their arms and legs in a swimming motion, which makes them look like natural swimmers.

"These reflexes don't mean the baby can swim, though," says Wagener.

Babies aren't old enough to hold their breath intentionally or strong enough keep their head above water. In addition to the risk of drowning, it's dangerous for an infant to swallow large amounts of pool water.

Still, many infant swim programs rely on these reflexes to help babies "swim." However, the American Academy of Pediatrics (AAP) doesn't recommend swimming programs for children younger than 1 year old.

After the age of 1, the AAP suggests checking with your child's doctor to find out if your baby is ready to participate in a swimming program. If she is, ask the doctor for a recommendation for the best type of program for your child's developmental level.

Even though your baby can't swim, some infants really enjoy splashing around in the water. So feel free to make playing in the pool a family affair - just stay hands-on whenever you take your baby into the water.

Abstract

The plantar response is a reflex that involves not only the toes, but all muscles that shorten the leg. In the newborn the synergy is brisk, involving all flexor muscles of the leg; these include the toe 'extensors', which also shorten the leg on contraction and therefore are flexors in a physiological sense. As the nervous system matures and the pyramidal tract gains more control over spinal motoneurones the flexion synergy becomes less brisk, and the toe 'extensors' are no longer part of it. The toes then often go down instead of up, as a result of a segmental reflex involving the small foot muscles and the overlying skin, comparable to the abdominal reflexes. With lesions of the pyramidal system, structural or functional, this segmental, downward response of the toes disappears, the flexion synergy may become disinhibited and the extensor hallucis longus muscle is again recruited into the flexion reflex of the leg: the sign of Babinski. A true Babinski sign denotes dysfunction of the pyramidal tract, and should be clearly distinguished from upgoing toes that do not belong to the flexion synergy of the leg. Correct interpretation of the plantar response depends only to a minor degree on the method or site of stimulation of the foot. It is therefore most important to assess the response in the entire leg.

What reflexes should be present in a newborn?

Reflexes are involuntary movements or actions. Some movements are spontaneous and occur as part of the baby's normal activity. Others are responses to certain actions. Healthcare providers check reflexes to determine if the brain and nervous system are working well. Some reflexes occur only in specific periods of development. The following are some of the normal reflexes seen in newborn babies:

Rooting reflex

This reflex starts when the corner of the baby's mouth is stroked or touched. The baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking. This helps the baby find the breast or bottle to start feeding. This reflex lasts about 4 months.

Suck reflex

Rooting helps the baby get ready to suck. When the roof of the baby's mouth is touched, the baby will start to suck. This reflex doesn't start until about the 32nd week of pregnancy and is not fully developed until about 36 weeks. Premature babies may have a weak or immature sucking ability because of this. Because babies also have a hand-to-mouth reflex that goes with rooting and sucking, they may suck on their fingers or hands.

Moro reflex

The Moro reflex is often called a startle reflex. That's because it usually occurs when a baby is startled by a loud sound or movement. In response to the sound, the baby throws back his or her head, extends out his or her arms and legs, cries, then pulls the arms and legs back in. A baby's own cry can startle him or her and trigger this reflex. This reflex lasts until the baby is about 2 months old.

Tonic neck reflex

When a baby's head is turned to one side, the arm on that side stretches out and the opposite arm bends up at the elbow. This is often called the fencing position. This reflex lasts until the baby is about 5 to 7 months old.

Grasp reflex

Stroking the palm of a baby's hand causes the baby to close his or her fingers in a grasp. The grasp reflex lasts until the baby is about 5 to 6 months old. A similar reflex in the toes lasts until 9 to 12 months.

Stepping reflex

This reflex is also called the walking or dance reflex because a baby appears to take steps or dance when held upright with his or her feet touching a solid surface. This reflex lasts about 2 months.

What is the palmar grasp reflex?

One of the most important infantile reflexes, the palmar grasp reflex refers to a baby closing his fist around anything that is placed in his tiny palm. If you place your finger in the palm of your newborn, he will grasp it, and if you try to remove your finger, the grasp becomes tighter [1]. The reflex is strong enough for you to lift the baby up if he is grasping the fingers of your both hands. However, it is just a reflex with your baby having no control over it.

Newborn palmar grasp reflex test video

The fine motor reflex is tested at the hospital, along with a number of other newborn reflexes after your baby is born [2].

When does the palmar grasp reflex occur?

Babies are born with the palmar grasp [6] with the reflex starting to develop during the 11th-15th week of pregnancy, as your baby grows within the womb [3].

When does the grasp reflex go away?

It gradually disappears after the baby reaches 2-3 months of age [4].

Why do infants have the palmar grasp reflex?

The purpose of the grasping reflex is believed to be to prepare the baby's hand muscles for developing voluntary grasping in the months to come [5].

An absent or abnormal palmar grasp reflex may indicate a neurological defect or some motor nerve damage (e.g. cerebral palsy [7]) present at birth. However, since the presence of the reflex is tested at the hospital, any abnormality can be attended to as soon as it is discovered.

The Moro reflex may be observed in incomplete form in premature birth after the 28th week of gestation, and is usually present in complete form by week 34 ( third trimester)[citation needed ]. Absence or asymmetry of either abduction or adduction is abnormal, as is persistence of the reflex in older infants, children and adults.

The sucking reflex is probably one of the most important reflexes your newborn has. It is paired with the rooting reflex, in which a newborn searches for a food source. When he finds it, the sucking reflex allows him to suck and swallow the milk.

Your baby does this without thinking about it because it's an innate instinct that is actually quite soothing to him as well. Some babies do have a little more trouble with it, however. There's a simple way you can test your baby's sucking reflex and things you can do to work through sucking problems.

The Sucking Reflex

The sucking reflex is one of seven natural reflexes newborns have. These are essential to their first few weeks and months of life. As the months pass, they begin to consciously do the actions and become able to control them as they develop.

The sucking reflex is essential for feeding. Babies begin practicing it in the womb and it becomes fully developed by 36 weeks. This is why you may have caught a glimpse of your baby sucking his thumb or hand on the ultrasound. It's kind of like a warm-up exercise for the real world.

While you may think of sucking as a simple process, it actually occurs in two steps. First, the baby holds the nipple between his tongue and the roof of his mouth. Then, he will actually begin to suck by moving the tongue up and down. The action is the "expression" of milk, which supplies the food.

Test the Sucking Reflex

If you touch the roof of your baby's mouth with your finger, a pacifier, or a nipple, he will instinctively begin sucking. Around 2 to 3 months of age, your baby's sucking will be a result of conscious effort and no longer a reflex.

Keep in mind that every time your baby exhibits this reflex, it doesn't necessarily mean that he's hungry. Sucking is a soothing, enjoyable activity all by itself. Babies also have a hand-to-mouth reflex that goes with rooting and sucking and may suck on fingers or hands.

Breastfeeding

Some mothers are slow to start breastfeeding and it may be because you're not triggering the sucking reflex.

It's not just the nipple that needs to go into your baby's mouth, but a fair amount of your areola as well. If you just have the tip of your nipple in his mouth, it may not be far enough back to stimulate the sucking reflex. Also, the milk sinuses won't be properly compressed by your baby's tongue and jaw.

Preemies and Sucking Problems

Premature babies may have a weak or immature sucking ability because the reflex has not fully developed. You may notice a combination of sucking issues, including:

Disorganized or inefficient sucking patterns

Weakened lip seal

Impaired tongue shaping or movement

Weakened stability of the inner cheek

Trouble synchronizing the suck and swallow with breathing

The last point is part of a complication that affects preemies known as Infant Respiratory Distress Syndrome (RDS). Babies with RDS have difficulty synchronizing their sucking, swallowing, and breathing. This can have a negative impact on feeding as they can't withstand long feeds and tend to tire easily. As a result, the newborn could be at risk of poor nutrition.

The sucking reflex often develops in premature babies over the first few weeks, even by the time they reach their original due date. Until then, they're fed via feeding tubes. Researchers continue to look at the sucking reflex and its relationship to swallowing and breathing. The hope is to develop possible therapies that can help premature babies better develop this essential skill.

A Word From Verywell

Knowing how the sucking reflex works can help you solve any breastfeeding difficulties you may be having with your baby. Sometimes simple things like a change in position can make a big difference. If you have questions or are concerned that your baby is not getting enough food, contact your doctor. You might even find a lactation consultant helpful.

2.2.2. Abnormal Responses

In general, a primitive reflex in infants is regarded as abnormal when it is absent or diminished during the period it should be actively elicitable or lasts beyond the normal age limit for its disappearance. An exaggerated reflex can also be abnormal. The response of the palmar grasp reflex may be less intense during the first and second days after birth [ 18]. The absence of this reflex usually reflects peripheral (i.e., root, plexus, or nerve) or spinal cord involvement, especially regarding asymmetrical responses [ 18, 30, 31]. However, lesions of the upper brain structures also can affect the response. The response may be increased and retained longer, compared with that in normal infants, on the affected side(s) of the upper limb(s) in infants with spastic hemiplegia or quadriplegia, whereas it is very weak in infants with cerebral palsy (CP) of the athetoid type [ 26, 27, 32].

The clinical value of the plantar grasp reflex in infants has been investigated in more detail than that of the palmar grasp reflex. In 1932, Brain and Curran [ 33] reported two cases showing no response at the age of 6 months who both suffered from bilateral marked spasticity and one case showing a vigorous response at the age of 2.5 years who suffered from congenital choreoathetosis. They also investigated the reflex in 59 patients with Down's syndrome, ranging in age from 1 to 45 years. They discovered that up to age 20 years, the response was present in 25 of 42 patients and, after age 20 years, in 3 of 17. We analyzed 617 infants (291 term and 326 preterm) whose plantar grasp reflex was examined before 1 year of age [ 5]. Their diagnoses were confirmed by follow-up examinations and comprised normality in 458, CP in 78, and mental retardation (MR) in 81. We obtained several results: the reflex reactivity in infants with CP of the spastic type was significantly reduced; infants with CP of the athetoid type exhibited an extremely strong retention of the reflex; infants with MR also exhibited a tendency for prolonged retention of the reflex; the reflex profile in infants with CP of the athetoid type with spasticity, or of the ataxic type, was not different from that in normal control subjects. Other authors also reported the characteristics of the plantar grasp reflex in children with neurodevelopmental abnormalities of various types, and their results were well consistent with ours [ 26, 27, 34].

A reduced or negative plantar grasp reflex during early infancy can be a sensitive indicator of later development of spasticity. Of 2267 infants whose plantar grasp reflex had been examined before 1 year of age, we analyzed the neurodevelopmental outcome in 47 infants exhibiting a negative response during the first 6 months of age and in 46 infants exhibiting a significantly reduced response at ages 1 to 4 months [ 6]. The diagnoses comprised CP in 75, MR in 7, borderline intelligence in 2, motor delay in 1, and normality in 8. Of the 75 cases with CP, 69 had the spastic type and 4 the athetoid type with spasticity. The total number of patients with CP of the spastic type or the mixed type with spasticity among the entire 2267 infants in this series was 107, and 73 of these 107 patients with CP with spasticity (68.2%) exhibited a negative or reduced response during early infancy. In the remaining 34 infants with CP with spasticity who exhibited a normal response during the corresponding period, the extent of motor disturbance was significantly milder [ 35].

A high concordance between the side of an abnormal plantar grasp reflex during infancy and the laterality of the disturbance of motor function in children with CP of the spastic type was demonstrated [ 36]. The side affected, or more affected, in motor function was in accordance with the side that exhibited a diminished or more diminished response in most subjects with spastic hemiplegia, diplegia, and quadriplegia.
