I don't think so. I just waited to find out the sex and then started. Plus you have plenty of time to research stuff and change/add to the registry. Go for it!!
I did! Start early so you can compare and shop around. You'll get really overwhelmed picking out stuff. Start and take your time. Just don't share it until you are done or almost done
I did mine today! I'm only 16w4d but know sexes & am having my shower in July. With twins, I'm afraid I'll go earlier and/or be too big to do it much later.
