DSS is 11. My DDs are 5 & 3. Its been a problem for a while now but until I was 100% it was DSS, I couldn't decide how to act on it. Everytime he uses the toilet, he doesn't put the toilet seat up, and he pees ALL OVER it. He's only here 4 days a month, more during holidays, and it only occurs when he's here, and after he's been to the toilet.
Am not sure how to broach it with DH. I have zero experience with boys other than my almost 4YO DN. AIBU to expect DSS to either lift the seat or clean the seat?
