Sorry if TMI, and for posting in AIBU but know its high traffic area.
DS is 6. He normally empties his bowels every 3-4 days. Sometimes its not very easily but as he's never been in any pain I've just monitored it as I have IBS. DS eats a very good diet, drinks plenty and excercises regulary.
Yesterday he was very tearful and I noticed his stomach was noticably distended under his clothes. He wanted a poo when out but couldn't go nd I noticed smearing on his underwear - leakage?
He woke up this morning and discovered he'd poo'd in his sleep. It was quite hard and large and he is adament he didn't know until he woke up. TBH I have no reason not to think this is true as if he wets the bed (not very often) he'll just come in with me.
This morning a few times he declared he was desperate to poo but when he got there couldn't go. He has been now 4 times today and each time has had such an urge he has soiled. 
He is not in any pain or seeming to be bothered by this. He has not eaten a lot today but I've made sure he's had plenty to drink (non dairy) I think he has been constipated and this is the clear out?
WWYD from here?
