My baby is 4 month 20 days old. How do I check the development of his digestive system? He poops almost daily. Does that means his digestive system is ready to accept cow milk and other solid food?

A. a baby has to be given only exclusively mothers feeding their formula milk to the baby in case of no mother's milk after 6 months of age cows milk to be given only after one year of age weaning foods after 6 months of age
