My daughter is just over 5 months. She was pooping really infrequently for the last few months - on average every 4 days I'd say. About a week ago, she went 6-7 days without pooping. I was about to call the Doctor and then she went. Since then (a week ago, she's gone more like twice a day). I'm worried only because it's such a change from 'normal' for her. She is eating alright, has wet diapers, and seems okay (as fussy as normal!). Her poops are a bit more liquid-y but not really different otherwise.
