DSD pees the bed. I try helping, being supportive, doin hours of fucking research on here and online, suggesting all sorts of things to do, trying to be supportive and offer advice when he gets stressed out/de up when it happens. (Will point out though that he doesn't show he's fed up in front of her, I get the brunt of that). All I ever get is snapped at, told how stupid my suggestions are, the 1001 reasons why they won't work. Before I tried helping he didn't even have a waterproof sheet on the bed, and didn't think it would be useful until I bought one and put it on her bed.
Basically because I don't have children my suggestions and ideas can't be as good as his. Even though he doesn't have any.
So cue this morning, DSD has had an accident. While she's in the bathroom he starts with the talk like how can somebody have that much pee, because she went before bed and I got her up for a pee at 10pm. I tried to explain about hormones not being produced and get snapped at that he doesn't need a science lesson.
So I said that I'm not helping at all with this issue any more. I've tried helping and it's apparently not helping him, so I'm just going to leave him to it. He seems annoyed with me for being over dramatic. AIBU?
