When did you ladies start your baby shower registries? I'm planning on doing one at target,Walmart, and babies r us just because mine and my boyfriends family and friends live 2 hours apart and not all areas have the same stores. We will find out at 19w2d what we are having and I'm going to have to resist the urge to go immediately after. Lol. I plan on having my baby shower at 30 weeks. Just because I don't want to be super huge and close to popping while having to deal with all those people and then having to put everything away. I'll probably send out the invites a month in advance so around 26 weeks which will give me about 7 weeks in between finding out the gender and sending out the invites. Did you ladies make yours right after you found out or did you wait a few weeks?
