I saw this on BBC earlier and I was thinking.. their kid tells them something like that.. and they don't grab a chair and sit in the room with her for a couple of hours when it is sleepytime???? (ps: watch Bluey - Sleepytime - irrelevant but great) They didn't lay a couple of blankets on the floor and and sleep next to her bed ONE night just to show her that everything will be alright and there is no reason to be worried? She was complaining to them (up to) 8 months? UUUfffff
