With my second DC, there was a sign up in the scan room saying “Please don’t ask the sex of your baby as we will not tell you”. I wasn’t going to ask anyway, but personally I think that’s best.
With my third DC, ex was obsessed with knowing the sex and we were allowed to ask but even then it was made clear that this wasn’t a definite answer. The guy even said that they wanted to make sure we understood that as some people could be very disappointed if they ‘got it wrong’.
Even if a woman didn’t ask the sex on a scan, she might still build up an idea of the sex by thinking that she was sure she was having a boy, people telling her the way she was carrying her bump made it ‘definitely’ a girl, saying she had bad morning sickness and ‘people only got that with girls’, etc etc.
The way to stop all this is to tell yourself regularly what we all know - it doesn’t matter as long as they’re healthy, and they will be their own person and might not even fulfil your idea of a girl or boy and the things you planned to do with them.
So, yes, I understand your feelings but you need to sit and acknowledge them, cry if you need to - then move on. Your baby was always as it was, even when you were wrongly told it was the opposite sex. Nothing has changed. XX
