My almost 2 months old baby who is on partial fm and bm has not pooped for 4 days. Is it normal? Or is there anything I can do or give him?

At 2 months old, a breastfed baby should be pooping 4 times a day and a formula-fed baby will poop about 2 times a day, once every 3 or 4 days. Perhaps your baby is constipated? Maybe you can try the following exercises to see if there are any improvements? - While your baby is lying on his back, gently move his legs in a forward, circular motions as if he were pedaling a bicycle. This should help "move" things along. - You could try massaging baby's belly. Place 3 finger-widths below her navel on the lower left side and apply gentle but firm pressure with your fingertips. Maintain gentle but constant pressure for about 3 minutes at a time. Be really reallly gentle.
