As soon as you want! There are millions of names to choose from and tons of resources out there for you to sift through. If you don’t have anything in mind or you’re indecisive by nature, you should probably start talking names with your partner early on in your pregnancy. Whatever you do, don’t wait until the last minute — you don’t want to be caught off-guard if baby decides to come early, and you definitely won’t want any added stress in those last few weeks if you can’t seem to decide. Many couples wait until they find out the sex of their baby to start looking, since it makes it easier to narrow the options more quickly.
