[QUOTE=samantha3;2637 3]Sometimes we chat/vent about childcare ideas/parents who bother us etc, but it is pretty weird that he is doing this (he is at home on a mat leave with a baby and an older child who is about 3....)QUOTE]

Do you think he is hoping that the two of you might include him or at least include his 3 year old who probably is driving him crazy. Is there a chance it is the child that is opening the door but can only open it as far as the deadbolt chain and dad is too busy to notice or do anything about it - especially if it keeps the child entertained.

If the wife thinks he is ok with the two kids at home and he seems to be managing he probably isn't that bad a person to have around but I'm sure he is very nervous about asking if he can be included. What if after daycare hours maybe even when the wife is home or even talk to the wife first with the idea we know he is there with the kids and well we get the feeling they are watching us play outside and wondered if they might like to come out when we do so your son could play with the other kids reminding her of course that the dad must remain out the entire time too since you can not take any responsibility for the child. I know it seems creepy but it could be more a case of lonliness than anything else.
