telling family

I just found out I'm expecting my second baby and want to tell family on Mother's Day! 
With my first we told them as soon as I started puking non stop a week after my positive pregnancy test but this pregnancy I feel good so I think I can hold off an extra few weeks but I also am so excited and want to tell everyone know. My fiancé wants to wait until we have the gender but I know I can't wait that long.
When did you tell? And what's a cute way to tell them including my toddler?
