My son has been pooping just fine now for a while since I've upped his miralax and intake on fiber. Friday he was literally a pooping machine and I hadn't even given him miralax in 2 days just prune juice in his bottle. Now he's back from his sperm donors pushing and crying trying to go and it hurts me. Which means guy didn't give him miralax and or prune juice or he fed him gluten which my son isn't suppose to eat as he's allergic and may also have Celiacs disease. Guy doesn't listen to anything I tell him and now my son pays for it. The clothes thing yesterday now the BM thing today I'm about to go crazy psycho on his ass and I really don't care. I want to tell him what a piece of shit dad he really is! 😡
