I know it's normal for exclusively breastfed babies to go a few days without pooping. However, DS is 17 weeks old and has pooped 2 or more times every single day of his life. Then the past two days, nothing. He is eating like normal, we just had a check up yesterday (before he'd gone a full 24 hours so I didn't even mention it) and he was fine. He doesn't seem to be in any discomfort, I'm just a bit concerned because it is so unusual for him personally.

Am I just being crazy? Anyone else's LO have a similar pattern?
