my girl's poop patterns changed after she started on solids. She used to fill the whole diaper, but now, it's like what you're experiencing, a bit of play dough poop now and then. Sometimes, she doesn't poop every day. If she stores up her poop, she will have quite a lot at her next poop session.
I only get worried when she passes out really watery poop that is just coloured water with no solid poop in it. She kenna this type of poop after she was given some table foods by some pple.
