To think he should knock.......

FarNorth thank you. I have just read your post to DH, his response.....

"Hmm, I suppose that's true"

Also you might need his help over something in the future. FiL always says to me, leave the door a little bit open, so I do try to, and he has been right.

I agree with Mishap. Making him knock could make the situation seem more strange to the GCs.

I can understand why your OH feels he ought to knock - but it certainly is not something to rock the boat over - keeping a good relationship so the GC can still be a part of your lives is far more important.

I'd just lock the door so you have to let him in.

He's done plenty to upset DD. DH doesn't care if he upsets him I'd rather keep the peace.

Anya Our back door is always unlocked it is the other side of a 6" solid gate.

It wouldn't bother me unless the split was acrimonious and he was trying to make life difficult for DD

I think he should knock and then walk in, if the door's unlocked. But as jane says, it's not worth making an issue out of.

I think it would be a bit sad, understandable but do you want to make him feel awkward? Because he will feel hurt.

Wouldn't bother me in the least, when he's expected and come to collect his boys. My SiL has his own key though the situation is different as there's no family split. If he was just turning up without a reason, then perhaps he ought to knock.

Why are your doors unlocked anyway? Anyone could walk in.

Yep!!

I with your DH! Not sure I'd say anything but, maybe, lock the back door when he is due - now the clocks are going back and everything!!
