DC1 is 10 and gets into bed with me (early!) a few mornings a week to have a snuggle. Sometimes he'll doze off for a bit, other times he chatters until DP wakes up and tells him to go and get breakfast, or until DD arrives and throws him out so she can jump in. I love our cozy starts and will be sad when he stops.
What sort of she do you reckon he'll stop? I can't imagine him doing it at 18 but if he did then we'd probably have to get a bigger bed
