Just found out second DC is a boy so went round to FILs house with DD (3) and told her to tell him.
His reaction was... 'ooh we're getting one with a willy!' DD started repeating the word willy over & over... I was a bit shocked so said something along the lines of 'don't say that silly' when he piped up with 'well what do you call it? A tail?'
AIBU when I say that it was completely unnecessary? There's not much point telling DH as he'll just say that's the way his DF is.
He also asked DD if she'd had her boobies out when we'd been on holiday recently. I'm not a complete prude (I don't think)? But people saying things like this to a 3YO really make me uncomfortable.
