YANBU - I have a couple of sets of friends who are not allowed round before my 3 yo is in bed now.
Sweets, silliness, DVD's of films that they haven't seen and want to, but the guest isn't prepared to leave them and have them returned, they have to watched right then....
Oh, and the 'off-switch' ... wind her up and then just expect her to stop and let them talk... leaving me to tell her off and upset her when she, understandably, won't.
I tried explaining after it happened the first couple of times that it needed not to, nicely, away from the child and the moment - esp the 'treats' - and it just did not go in....
No comprehension of why I don't want her staying up till 10pm when we all have to get up at 7am. No comprehension of why I don't want her eating that giant bag of haribo at all 10 minutes before bed, and when I've already done teeth/face/hands etc.... and no comprehension of how fucking annoying it is when they did 'oh, well, Aunty/Uncle XX brought these but I guess Mummy says no....' AFTER my DD has seen them...
It drove me nuts, so now they aren't allowed round until after bed. It means they don't see her nearly as much, of course, which is a shame, but it was the only thing I could do.
Of course now I get 'oh, didn't you keep her up for us...? But we brought....'
