AIBU? My husband and I are TTC. We were looking after my niece a few nights ago, and we set up her travel cot in the living room. After she went to sleep, we went to our room to DTD. While we were DTD, our NDN who we are really close with (and who knows my niece and her parents well) let himself in and my niece was fussing in her cot. When he realised what was happening he picked her up and took her home to his flat in the same building.
When me and my husband were done DTD we freaked out that my niece was missing, but luckily we figured out where she was before anything serious happened. I was terrified though for a few minutes.
YABU - we shouldn’t have TTC while in charge of a baby
YANBU - it’s fine, baby was safe and neighbour/friend should have left you to it
(FYI - I love Friends, this is tongue in cheek)
