Mu baby is 2 mmths and 21 days old he is not drinking enough milk .after milk he is playing good for 2 hrs and suddenly staring to cry aching his back backwards and not drinking milk . What should i do

A. A child can actually cry because of severe stomach pain and that is when they actually move their body like this so give a medicine for stomach pain and once the child will settle down the child would be playful and will also take a feed properly after that
