Hi all, I came home yesterday from a lovely day out with DD to find my DH in the laundry room and my 9 month old baby alone in the bath in the bathroom next door. He was in one of those bath seats so my DH thinks he was perfectly safe and tells me I'm overreacting and overcautious. He says he only left him for a few seconds. DH had no line of sight into the bathroom at all. AIBU to be worried about this? Thanks.
