Royal sources already confirmed that the heater incident happened, and that a faulty heater was smoking.
That's very very dangerous. If it hadn't been caught in time then it would have caught fire.
The fact Archie coincidentally happened to be out of the room is irreverent. The fact is a faulty, dangerous heater was in a baby's nursery. It could have started smoking at any time of the day or night, it could just as easily have started smoking at 1am with everyone asleep, meaning that Archie likely would have been killed or the smoke not caught before it turned into a full blown fire.
I can 100% promise if anyone on Mumsnet started a thread to say "AIBU to be upset that I'm abroad for a work trip with my baby, and an unattended faulty heater in my baby's room started smoking" it would have 100% YANBU rate and probably dozens of comments about how dangerous it is, that the OP should remove her baby, go home, sue the hotel, baby could have died.
Just because it's Meghan and you hate her and everything she does, you're defending a baby being endangered.
I pray none of you have children or are allowed around children.
