I found out with both of mine. I love it because I like to be extra prepared lol. We choose a name and make a painted name decoration for their nursery wall, buy clothes and stuff (because I get sick of the white/grey/beige) and I feel like DH and I really bond with baby and identify a bit with who this little person is.

The hardest thing for me is I don't like others to know, I like the sex to be part of the announcement when baby is born and it's so hard not to slip up!
