So I will be calling a child therapist and the doctor tomorrow but SS just came home from a one night sleep over with the grandparents only for Dh to find SS soiled and urinated in two pairs of underwear. He is 7 and has had some regression (wetting the bed) for the past 3 months or so. We have just been sleep training him and thought nothing of it, it was improving- but pooping in his pants seems a little more severe. SS hid the soiled underwear but when asked about it said he pooped in the evening right when we dropped him off and didn't tell anyone- he slept in soiled underwear!We went from 100% custody to 50/50 with BM last month and she announced her pregnancy- we have not yet. Other thoughts: SS absolutely struggles to make friends, he was academically far behind (couldn't read) before we got custody, he didn't know how to wash himself before we got custody, you probably remember my posts about his sloppy outfits- I would assume from his clothes (never had any outfits that fit, shoes had holes) and appearance he was pretty neglected by BM before we got on her about it. Ideas? This is kind of scaring the crap out of me. I hate for my mind to go there but could someone be abusing SS?! Could this be a learning disorder?! Any thoughts would be MUCH appreciated

Re: WTF SS
This exactly.
My mom started wetting the bed again in grade three because her little sister was born and her other little cousin came to live with them. My mom felt a tremendous amount of shame and embarrassment but now, at nearly 60, and looking back she thinks she was reacting to going from being the baby of the family to missing her mothers attention. I'm not saying this is the issue, but certainly something to consider. I think getting SS checked by a psychologist and GP would be great first steps to figuring out what's wrong.
I started wetting the bed at age 5 and it pretty much continued until I was 9. I'm trying to freak you out BUT my uncle began abusing me at age 5 until it was found out at age 9.
Please don't make him feel bad about it or like he did anything wrong. I remember waking up wet and I would freeze in the bed and pray to god that I was imagining it. Its truly a horrible thing for a child to have to go through.
He may not be being abused BUT he may be frightened of going to BMs or his grandparents. Maybe he is confused and doesn't know whats happening and when you are coming for him etc. He may be scarred to talk to them or ask for help. He obviously does not feel confident even to tell them he needs the bathroom.
My heart goes out to him.
We will be taking him to the doctor and counselor and keep you updated. As far as the grandparents he stays over there with all the cousins once a month and begs to go the oldest grand kid is 12 and the youngest is 3. There are five altogether. He's been doing the once a moth routine since he was born.
Right before Christmas Bm said he had diarrhea all over his pants and shirt and coat in her custody but that's the only other time we heard about a similar incident.
We try not to shame him but dh told him of he had an accident we would keep it a secret and not tell but he needs to tell us because it's not healthy to walk around like that. As a kid I was having random accidents until I was 7 or 8 because I would play too long and not go but I would immediately ask an adult for a change of clothes. The upsetting thing is he will just sleep in his sheets all night and now he's just continuing to play in soiled underwear.
For the record there are not outward signs of physical abuse (bruises, cuts) but that doesn't mean something we don't know isn't occurring
My DD started peeing her pants frequently at age 7. She had been potty trained since 18 months. That year we ended up having her evaluated by a neuropsychologist (for many reasons, but that is just one of them) and that's when she was diagnosed with Aspergers. There is an increase prevalence of enuresis and encopresis in kids with ASDs and ADHD. Luckily, for her, it only lasted that year.
Also, my oldest SS is 9 and still deals with enuresis on occasion. He has ADHD and has also had 3 kidney stones so either of those could be the cause in his case. He usually wears a watch with a timer set to go off every hour to remind him to go.
There can be many underling causes to it's best to consult the doctor.
