Babies are born with reflexes that will help them transition to life and stimulate their growth and development. Reflexes are automatic and involuntary responses to stimulation. Babies movements are better understood when one is aware of what these reflexes look like. We can also assist our babies with learning, interaction and development by responding appropriately to these reflex movements.
MORO or STARTLE REFLEX: Sudden movement, sound, or light can cause a baby to bring out their hands and feet followed by a deep breath and bringing hands and feet back in toward the body and clenching their fists. This reflex should disappear at about 2 months.
TIP: Setting off this reflex can make your baby uncomfortable and irritable therefore avoid unpredictable movements, loud noises, and sudden light transitions when possible. Another trigger to this response is your infant’s uncontrolled hand and foot movements. Keeping your baby swaddled is another way to decrease unnecessary startle responses.
ROOTING REFLEX: By touching a baby’s cheek or mouth a baby will turn their head toward the touch. The baby’s mouth will open and their tongue will move around, the baby is preparing to eat. This reflex should disappear at about 4 months.
TIP: Before your infant develops control over his body movements, flailing arms can stimulate the rooting response. This can be distressing for your baby especially during feedings. You can keep your baby’s arms wrapped in a blanket during feedings to eliminate this problem.
PALMAR GRASP: Light touch or pressure to the palm of the hand will stimulate a fisting motion. This reflex should disappear at about 6 months.
TIP: You can use this response to help teach your baby to hold rings and small rattles. Encourage him to bring them to his mouth and eyes to explore, learn, and look at.
PLANTAR/BABINSKY REFLEX: When the sole of a baby’s foot is stroked the toes will spread and curl and the foot will turn slightly inward. This reflex should disappear by the end of the first year.
TIP: Make sure your baby gets enough tummy time because stimulating this response on the floor is one way that helps your baby learn to crawl and eventually walk.

ASSYMETRIC TONIC NECK REFLEX: When a baby is laying on his back if his head is turned to one side his arm and leg on the side he is looking at will stretch out and the opposite leg and arm will bend. This reflex should disappear at about 4 months.
TIP: This reflex will help your baby develop eye hand coordination. Pay attention to your baby’s head and hand position when you offer him a toy, introduce the items at arms length for him.
It is a good sign when these reflexive movements disappear. The disappearance of these reflexes are necessary in order for a baby to begin to efficiently using his body to move and learn in his environment.
