Baby shower invitations

SD asked me about her baby shower, pretty much where she wants it held.  I told her she can hold it in our house.  DB and I do not mind at all.  She wants to get the invitations ready by March or April the latest.  I can see she is very excited about this pregnancy.  DB and I are hoping the baby will be a boy, but BF wants a girl.  Whatever the baby’s sex is it is fine as long as he or she is healthy.
