I'll try my best to explain what they look like. First, a bit of background. DS has had digestive troubles since shortly after birth. Found out a few months ago about some food intollerances (dairy, wheat, eggs, sugar, oranges, lemons). He's been off all of them for around 3 months. So starting about 3 days ago he has been pooping these white "sacks" about the size of a peanut. They are mixed in with the poop. They are gelatiny like and when you squeeze them, there's a bunch of yellow goop inside. He had the same thing before for about a month and the doctor wouldn't even look at them, said to just see what happened. He doesn't eat grapes, and he eats nothing else that would resemble what these sacks look like. He's been complaining about a sore belly and he has had some mucous in the poop as well. Any ideas?
