my baby is two months old and after tummy time he was crying so what is issue.

A. Hello good afternoon !! Tummy time after 2-3 months is best as they try to roll over ,tummy time helps them in holding the neck ,head ; crawling,strengthening abs. As the baby is crying after tummy time then it might be painful. So wait for 2-3 weeks,once the starts roll over, then start tummy time 5 minutes gradually increase time.
