Pooping less frequently since starting solids.

[jessmke]

Is this normal? Isla used to be very regular with a morning poop every day, sometimes it was every other day but never more than two days without pooping. Now she is going 4 or 5 days between poops, and then when she does go she has a poop-fest all day long. She doesn't seem to strain and her poops are still soft like toothpaste. She doesn't consume a lot of solids but I can tell by the stinky poops that she is eating at least a bit of food. She doesn't seem uncomfortable, although the night before she has a poop-fest her sleep is terrible so she might have an uncomfortable stomach. How often should she be pooping??
