My LO is EBF and I know it can be normal for them to go days without pooping. We are in Day 9 of no poop and I'm beginn by to get worried. He's eating normal and having plenty of wet diapers but it just seems like this is too long. He takes Zantac for reflux and I think this is a side effect. Has anyone else's baby gone this long without going? His last poop came after one week.
