Ever wonder why your child does certain things, as though by instinct? Here are some primitive reflexes your little one has already developed. Show
It’s a moment captured on countless cameras: You touch your newborn baby’s tiny palm and he grasps onto your fingerwith surprising strength, like he intends to never let you go. Maybe it’s a bit deflating to learn this fierce grasp is just a reflex, but it’s fascinating, too: Your baby is born with as many as 75 reflexes. Some baby reflexes disappear abruptly, usually between three and six months of age, while others are gradually replaced by more intentional behaviour. Mouthing reflexesThis cluster of reflexes is all about survival. Stroke your baby’s cheek, and she’ll turn toward your touch with an open mouth. This rooting reflex helps her find and latch onto a nipple. Brie Hoffman, who lives in Burnaby, BC, is mom to six-month-old Laura. “When Laura was a newborn,” Hoffman says, “sometimes I’d put her face up to my cheek when she was rooting, and it felt like she was kissing me.” Infants will also suck when the soft palate or mouth are stimulated. The gag reflex helps prevent choking: If something touches the back of her throat, her jaw drops and her tongue thrusts forward to push it out. Moro reflexEver seen a baby monkey clinging to its mother? It’s easy to see a remnant of that behaviour in the Moro reflex. If your baby is laid on his back too abruptly, feels his head is unsupported or is startled by a loud noise, he’ll throw his arms and legs forward as if grabbing on for dear life. This baby reflex still has some use, says psychologist Penelope Leach in Your Baby & Child: It tells you he’d like to be moved more gently. Stepping reflexAlyson Shaw, a paediatric consultant at Ottawa’s Children’s Hospital of Eastern Ontario, describes this puzzling (but cute) baby reflex: “If you hold the baby upright with her feet touching a firm surface, she will lift her feet one after the other as if walking.” Shaw says there is no known biological explanation for this particular reflex. “Laura is doing a lot of this stepping now,” says Hoffman. “If you hold her in standing position when she’s upset, she looks like she’s stomping her foot.” Righting reflexesPlaced face down, your baby will turn his head to the side, ensuring he can breathe. And while on his back, if a blanket falls over his head, he will twist his head and flail his arms to push it away from his face—a potential lifesaver. Galant reflexShaw describes this lesser-known reflex: “Hold the baby belly down, lying on your forearm and hand. If you gently stroke along one side of her spine, she will arch her body toward that side.” Baby reflexes are checked in an exam soon after birth, and at subsequent well-baby visits, to rule out neurological problems. “We confirm these reflexes are symmetrical, and that they extinguish at the proper time,” Shaw says.

Introduction[edit | edit source]The rooting reflex is an innate response of the head due to the stimulation of the face, mouth, or cheek by touching/stroking (the head is turned towards the side of the stimulus).[1] It is a brainstem mediated primitive motor reflex also called the frontal release reflex. This reflex has also been observed in the apes and other mammals.[1] The presence of the Rooting reflex has also been linked to altriciality-meaning that the newborns are unable to feed themselves (unable to source for food) with the help of locomotion. Therefore in response, the caregiver feeds the young one taking the reflex as a cue.[2] Stimulus[edit | edit source]The reflex commences when the corner of an infant’s mouth is stimulated by touching/stroking. [3] Response[edit | edit source]The newborn will turn their head towards the stimulus(finger or nipple) and open the mouth wide with tongue thrusting (tongue sits too forward in the mouth).[3] Duration[edit | edit source]The rooting reflex is present at birth (around 28 weeks of gestation) and disintegrates about 4 to 6 months (until the frontal lobe of the cerebral cortex matures.)[3] [4] The healthcare provider strokes the corner of the mouth of the baby and the infant turns their head towards the stimulated side. For eg., if the right side of the corner of the mouth is stimulated then the baby turns its head to the right side. Difference between Sucking and Rooting Reflex[edit | edit source]

What happens when you touch a babies cheek?For example, your baby is born with a rooting reflex that prompts him to turn his head toward your hand if you stroke his cheek or mouth. This helps him find the nipple at feeding time.
When the baby's cheek is stroked the baby will turn towards the side of his her face that was stroked?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.
When you touch a baby's cheek it will turn toward your hand and open its mouth this behavior is called the _____?Mouthing reflexes
Stroke your baby's cheek, and she'll turn toward your touch with an open mouth. This rooting reflex helps her find and latch onto a nipple. Brie Hoffman, who lives in Burnaby, BC, is mom to six-month-old Laura.
What are the 4 infant reflexes?Moro reflex. Sucking reflex (sucks when area around mouth is touched) Startle reflex (pulling arms and legs in after hearing loud noise) Step reflex (stepping motions when sole of foot touches hard surface)
