S.H.
what do you mean by his poop is not formed?
In a toddler/baby... the consistency of poop, is ideally like oatmeal. This was told to me/Hubby by a Pediatric Gastroenterologist. So, it is neither hard (balls) nor like runny liquid. But like oatmeal.
In a diaper, poop will not look "formed" because it is not dropping into a toilet... in a tube shape. Sorry for the graphic/yucky description. But that is what happens. In a diaper, poop will just be a clump of something.
So, this is either normal for him, nor not. And it also depends on what they eat each day. Has he always pooped a lot? Or is this something new? Is he perhaps sick with a bug?
I think, just ask your Pediatrician. It is nothing to be awkward about. They hear about all kinds of things. That is their job. And if you have a concern, you should ask them.
All the best,
Susan
