I’m pleased for the family but I’m worried she’s being slightly premature with her announcement, the sex really can’t be obvious at 12 weeks, what the sonographer suggested was the nub theory, 60% is just over half which isn’t much to go on and if they did as Helen suggest tell her that her baby was a girl at 12 weeks gestation I’d be somewhat surprised.
The only way to know for sure would be the Harmony test that someone mentioned above, which costs around £500. If they wanted to know that badly it would have been worth paying the extra to know for 100%.
I do hope the baby is a girl as that what they really seem to want.
