I'll set the scene...
Divorced from DCs dad. We have a very strained relationship. DCs are DS(3) and DTs(1). DS likes to watch Ryan's Toy Review on YouTube. Ryan has recently uploaded a video introducing his new baby twin sisters, Kate and Emma.
Well....last night, during his over night stay with ExH, DS decided to tell daddy that mummy has 2 baby girls in her tummy, we're going to call them Kate and Emma, and we need to move to a bigger house because there's no room here for all those children. 

ExH has got himself in a right strop over it. So this morning I've had to have an extremely awkward and utterly hilarious conversation with ExH, explaining to him that I AM NOT PREGNANT! (Apparently, the detail that DS went into was quite convincing as ExH still doesn't believe me!)
So, AIBU to make DS wear a gag when he goes to his dad's? Or at least BAN him from speaking altogether?
