We found out at the 20 week scan on the very clearly expressed understanding that we wouldn't tell anyone else as I wanted a suprise but he'd didn't. So this was the compromise.
But of course Mummy's boy of the century just told her when she asked :(
I really, really don't like her anyway. When question H says 'oh well she asked so I couldn't lie'. No?! But you lied to my face when you said you wouldn't tell anyone... That's ok obviously. heaven forbid Mummy should actually have to wait to find out.
AIBU to be fucking furious. I've not told anyone, obviously. I wanted this to just be between us, but it's not. Why does she have the right to know what the sex is? It's not her baby. I have realised so very clearly that he would much rather I be upset and annoyed than actually have to tell her that we are not telling people right now but she'll find out in due course.
