My baby pooped once a day and it was definitely firmer then when he was breastfed. He never cried when he pooped or seemed to be struggling so in knew he wasn't constipated and our peadiatrician said once a day or every other day was normal for formula. But call your dr if you're concerned.
She hasbt pooped since the morning what do i do
If she new to formula its most likely green because you changed her diet and she should poop 2-3 times a day until she 2 months then 1-2 times a day. Also her poop should be soft and smashed lookin. The green will turn to mustard yellow once she gets used to formula.
I didn't breastfeed but my daughter is on formula. She poops every other day, and it's mostly solid but still soft so it's not super hard...but firm.
