My DS has typically poops at least once (sometimes 2+) every 24-36 hours. Last week he went almost 5 days without pooping, which I know is not unusual for an EBF baby - he has pooped daily since then. What did seem unusual to me is that during and since the 'hold-off', DS has had really stinky gas - bad enough that others have commented on it. He is a farty baby, but typically it does not smell, let alone this bad. Nothing has changed in either of our diets, so I'm at a loss with the change.
