When my toddler was 1yo and awake crying around 2am at night in his cot and wouldn’t settle, my partner shook the cot like grabbed it from the end and shook it. He did it out of frustration as he was trying to sleep and tried to settle him but he wouldn’t settle. I was sleeping in a separate room in order to get a full night sleep and he told me this the next day. Ever since I’ve always been in the same room as my baby up until he was old enough to sleep in his own room. Is this unreasonable for my ex partner to behave this way? I am asking because we are now separated and he is asking to spend some time with our new baby and I wonder if it is safe to allow my baby to stay over at his overnight.
