Big Sister 👧

Patch • First they're sour then they're sweet.
I'm trying to figure out a special way to tell our 4 year old daughter that she's going to be a big sister! She's been asking us for a sibling for quite a few months (specifically twin babies) lol. She's even taken the time to pray to Jesus! I've looked all over Pinterest for ideas and they all just seem to look the same on there.
 Any of you have any cute ideas?
