Answer: 4. Turning their head toward stimuli when touched on their cheeks.
Step-by-step explanation:
The rooting reflex is an involuntary action practiced by newborns known as neonates. It is a situation whereby the baby naturally turns their face towards a stimuli, which could come in the form of a touch on their lips or cheeks, and then tries to locate the breast so as to latch on and suck ( or root ).
It helps the breastfeeding process because the baby does not have to be forced to suck, rather he naturally seeks the breast out. When approaching four months, this action begins to fade away.
