I have a new born and I woke up earlier and the flat was warm so I opened my window which is a ground floor flat after about an hour it's boiling in the living room but I thought it could be hormones so Got the themomitor and measured the room temp it was nearly flipping 30 degrees which doesn't make sense as the neighbour is out and it 15 this eve...she left her heating on full blast even tho she's gone out probs since 3 ish and she's just gotten back would AIBU to have a go at her? All my windows are wide open and its 24 atm the baby was dangerously hot. There was probably cues that she was hot but I'm a first time mum and a bit naive I wil be more aware in the future but she was not wearing lots of clothes nor did I think her heating would be on when she was out on a reasonably warm day.
