U have to do feeding properly as per lactation guidelines....

Which formula milk you r giving? If you breastfeed, you may have heard that your milk is divided into two types. Foremilk may be lighter, like skim milk. Hindmilk may appear fattier, like whole milk. More foremilk is produced at the start of a nursing session. The more time your baby nurses, the more hindmilk they’ll get. With some babies, if there’s an imbalance and baby gets too much foremilk, it may cause anything from gas to irritability. Your baby’s poop may be explosive at times. And it can look green, watery, or foamy.
