My wife and myself have a 10 year old boy in the room next door to us and a four year old in bed with us. Time what time. Haha what I have done is installed weather stripping or soundproofing to our door and a lock to keep the boys out and we make a nice little cradle against the wall pillow stacked to the ceiling for my daughter so we can at least have some resemblance of intimacy. I am not going to lie it is very awkward fooling around, doing the deed with the four year olds in the same bed, but sometimes you got to do what you got to do. The weird thing is we've never been interrupted by the two-year-old in the bed it's always the four-year-old excuse me 10 year old in the other room. He is not old enough to understand what's going on so he tries to how do I say interrupted or throw a fit when he knows the door is locked. It is very frustrating sometimes. We do send them to the grandparents but unfortunately by the time it gets to that point we're both exhausted that we just want to watch a movie. I don't have much advice but to find your own way and don't be embarrassed.
