Is it normal for baby not to poop for 2 to 3 days ?

I guess your baby's coming two months old? They have a pattern whereby either every feeding baby will poo or two to three days later will poo. And the day baby poo, it can be two to three times. Otherwise if this worry you do bicycle exercise for baby, massage, tummy time after every feeding for 10 mins. It helps with neck strength as well as digestion. Sometimes tummy too much wind or gassy therefore their decision process differs.
