Which is better substitute of mothermilk ... Is it cow milk or formula milk ...

Depend on age of baby. If he less than one year then offcourse formula milk . Because cow milk is more difficult to digest for small babies .. I didn't have enough breast milk and have to give my baby additional supplements from 1st day of feeding. I gave him firstly cow milk by doctors advice but my lo always have a hard stools because of the cow milk . So my doctor suggest me to go for a formula milk.. I used formula until my baby turn 12 months and then again I start cow milk and now he is totally okey with it.
