Hi all just coming in on the sex determination question. I have been told that if you are told it is a boy (when the genitals are fully formed of course after 16 weeks!!) that you are pretty much certain it is a boy but if they say a girl then hold off on buying pink as it could still be a boy. They can never be sure of a girl as those bits can hide and also be too small yet to see. A few of my friends have found out the hard way that lesson!!!
