My 5 week old baby has not pooped and its entering the 4th day. she does seem to be uncomfortable and does cry and moan. i am breastfeeding her for most of the day and at night i give her formula. should i be concerned? what can i give her?

Breast feeding: Breast fed babies may go several days before pooping. It's more difficult for babies to push, so they may strain and grunt at times. If the stool is hard, like little pebbles, try giving her extra clear fluid- water or Pedialyte. You can try some diluted apple juice (1/2 oz in 3-4 oz water). If that doesn't help, check with her doctor. We don't advise laxatives or other medications for babies.
