to be very angry that my DH let the children paint in the living room and make a blooming mess

[MimiSam]

I am far from houseproud, but I don't let the children (7 and 3) do really messy stuff in the living room. The 3 year old is a minx and loves to splash, pour stuff out and generally make a mess. DH knows I didn't want them to have the paint in the living room (told him distinctly), but he let them do it today and, surprise surprise, the 3 year old has splashed green paint over the walls. I got angry (with him, not them, they were in bed by the time I saw it), then was accused of blowing it out of all proportion.
He's cleaned it off as best he can and, to be honest, it doesn't look too bad now (can still see it a bit though), but it's the fact that he let them do it, knowing I didn't want it to happen, that really annoys me. AIBU?

a bit, yes. he's their parent too, it's his house too, and he made a decision to allow his children to paint and play.

I am going to be the only one who thinks this but it is because my opinion is that both parents have equal say in the house, the kids, everything and one parents doesn't give the other instructions in childcare or housekeeping.

He made the decision to let your shared kids play with paint in your shared living room and he cleaned up the mess. All is as it should be, imo.

I'd batter anyone that let the kids play with paint in the sitting room - DH or not

I sort of agree with Hecate, but I would also be pretty pissed off if I was the OP. I mean, yes, equal parent yada yada, but its generally obvious that 3 year olds, paint, and living rooms don't mix.

Well if he cleans it up I would say OK.

But tbh, painting in the living room?

Is there no where else more suitable?

Or does it mean that he can sit & watch telly whilst not really watching them?

I let my two year old paint in the living room. But I spread an old sheet out under the paper, and I sit down and paint with her, so if she strays from the Painting Zone I'm there to do something about it.

Agree with Hecate, but you're allowed to be miffed that it was a bit of a silly decision (and he probably wasn't watching).
