Congratulations on having a baby. 
It's strange when you're pregnant because you know only one thing about the baby and that's what is between his/her legs. And largely this tells you nothing about your baby. Their personality, their likes, dislikes, individual quirks.
And people will wheel out all sorts of nonsense. Usually stuff about girls liking pink or being nasty, bitchy, cheeky things. Or 'boys love their mummies' (especially at odds with the 'girls are yours for life, boys only until they get a wife' phrase which is also wheeled out). Or sometimes 'boys are like dogs'. It's gender bingo and largely irrelevant. All babies love their parents. People however seem to be surprised by how much boys have the capacity to show it. And it's all part of how we've been raised. People exclaim about cuddly boys but are not surprised by cuddly girls. When really they're just children and of course they seek out and adore physical closeness. They don't know they're men in training and they're supposed to be stand offish and not need cuddles/not show their emotions. And it's brilliant because they are who they are before they've been told they're not allowed to be who they are iyswim.
I have a 4yo dd who adores Marvel comics, getting muddy, dinosaurs, tractors and climbing trees. Her Dad is one of 3 boys and a girl. One of the boys is a professional ballet dancer, the girl plays rugby (for England in fact). None of the boys like football. Who they are is nothing to do with their gender.
You will love your baby like nothing in this world. Not because they're a certain gender, but because they are a unique, wonderful, amazing little creature.
