In my opinion I think it affects them a lot but it’s different for everyone but some people do change after that
There are many primitive reflexes for infants, but some of them are the walking/stepping reflex (they will attempt to walk by abruptly placing one foot out), rooting reflex (looking for a base or the nearest object to latch onto because infants are always looking for the breasts to breastfeed from their mothers), and swimming reflex (if placed over water, the infant will paddle their arms and legs).
Yes because she doesn't stop no matter what :3 hope this helps u 1
