We have a family member (BIL) staying who has got very very drunk. He's already fallen over, half asleep, into my son's (8 months) bedroom door, waking him (thankfully only briefly) and walked into hallway table, causing quite a crash. I am unable to get back to sleep now and am probably being silly but I am worried for my son having someone so out of control in the house. Currently sleeping outside son's bedroom to guard him (!) but it's not that comfortable! We don't have a monitor as it's a tiny flat. Am I safe going back to bed? PND so inclined to overreact, so please be kind! Husband sound asleep, very heavy sleeper. BIL is gentle kind guy and this is quite out of character.
