Research shows that slowing down your speech, speaking in a higher pitch and giving pauses for the baby to respond makes them smarter. Talking to children as much as possible from birth gives them a head-start and will help prepare them for school.
This is a note based on the book “Child Development” by Laura E. Berk”
“Baby smiled! He smiled at me!!!”
This was my reaction when my son smiled at me for the first time.
As naive as I was, I later learned that he wasn’t exactly happy to see me.
He was moving his face to express some emotion, but probably not intentional.
