You should send baby shower invites 4 to 6 weeks before the date of the shower. This gives your guests ample time to get a gift and save the date on their schedules. So, you'll have to choose your baby shower venue before that time, as well as have the gift registry ready. If you're having the baby shower catered, we recommend setting that up early as well since caterers can get booked up. Remember that if you send baby shower invites online, they'll arrive immediately, but if you send them via snail mail, you should account for a week or so for them to arrive. Give yourself plenty of time to get everything prepared, and everyone will be able to enjoy the baby shower that much more.
