This reflex occurs in slightly older infants (starts between 6 and 7 months [24] and become fully mature by 1 year of age) when the child is held upright and the baby's body is rotated quickly to face forward (as in falling). The baby will extend their arms forward as if to break a fall, even though this reflex appears long before the baby walks.

[31] Able to roll from both front to back and back to front. [31] Rocks back and forth and may crawl backwards. [33] Communication skills. Uses voice to get attention and to express emotions ...
The symmetrical tonic neck reflex (STNR) is a primitive reflex that normally emerges during the first month of an infant's life and is diminished by the age of 9–10 months. [1] It is a bridging or transitional brainstem reflex that is an important developmental stage and is necessary for a baby to transition from lying on the floor to ...
A list of reflexes in humans. Abdominal reflex; Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. Acoustic reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities.
Grasp reflex. Newborn babies have a number of other reflexes which are not seen in adults, referred to as primitive reflexes. These automatic reactions to stimuli enable infants to respond to the environment before any learning has taken place. They include: Asymmetrical tonic neck reflex; Palmomental reflex; Moro reflex, also known as the ...
Most human babies demonstrate an innate swimming or diving reflex from birth until the age of approximately six months, which are part of a wider range of primitive reflexes found in infants and babies, but not children, adolescents and adults. Other mammals also demonstrate this phenomenon (see mammalian diving reflex).
The asymmetrical tonic neck reflex (ATNR) is a primitive reflex found in newborn humans that normally vanishes around 6 months of age. It is also known as the bow and arrow or "fencing reflex" because of the characteristic position of the infant's arms and head, which resembles that of a fencer. When the face is turned to one side, the arm and ...
The tonic labyrinthine reflex (TLR) is a primitive reflex found in newborn humans. With this reflex, tilting the head back (extension) while lying on the stomach causes the back to stiffen and even arch backwards, the legs to straighten, stiffen, and push together, the toes to point, the arms to straighten (not bend at the elbows and wrists, and the hands to become fisted or the fingers to curl).
