Triggered by watching Waffle Doggy.
First episode is their wedding. Dad and son move in on the day of the wedding with Mom and daughter and son (8ish) immediately put in room with daughter (4ish). It's a while before he gets his own room.
Why wouldn't you try living together before the wedding and why didn't they give up their bedroom temporarily to give the kids privacy?
Who else? Doesn't have to be on CBEEBIES lol
