Eric has had some difficulty pooping lately. He has pooped once in the last six days. The most probable reason is the rice cereal he had. It's normal for rice cereal to cause some constipation (Anneli went 2-3 days at a time without a poop), but one poop in a week is a little strange. He doesn't seem uncomfortable, although his farts are STINKY. He's been sneaking out some silent ones, too. We've been giving him prune juice hoping to help the poop, but it doesn't seem to be working. Suggestions welcome.
