Ideas on surprising my husband

I had my first positive test this morning but I wanted to wait until this afternoon to tell my husband.

He got a cute diaper bag for me for Christmas (I had no idea) because he said he thought I would like it and I think he was hoping that I would surprise him with a positive.... well little did we know I actually was pregnant. I want to use the diaper bag to tell him, maybe set it on the counter with a sign saying “we’ll be using this after all...” does anyone have any suggestions or cute sayings I could use ???
