what is the personal development of a 0 to 4 months old infant?

Question

I need answers right now ASAP plsssss=)

Answer 1

From all indications, it is very, very important that an infant be subjected to a type of bonding with the mother/father, and also
be entertained with sounds and colors. It is important to try to develop a fun, playful manner while learning things. Stressed out babies usually reflect their environment. Babies are like "sponges", they soak up everything they see and hear.
Take care of the little one, it is our future generation.

Answer 2
