We didn't find out. For us, it was more important to have the surspire in the delivery room because life doesn't have enough of these kinds of happy surspires.Pros: we didn't buy a lot ahead of time, especially clothing that has a short time span to be used, we had fun selecting both boy and girl names, we liked to debate about if we thought it was a boy or a girl ( I called LO "Frances/Francis" in utero because it sounds gender neutral).Cons: people want to buy you gifts, but there's not that much gender neutral stuff out there, so we got lots of dupes that we had to exchange
