Small kids love bubbles almost as much as they love candy; so we decided to go with bubble wands again. They were a big hit last year. I got a pack of pink bubble tubes with heart tops at the wedding aisle at the craft store (who cares that it was intended to be a wedding day favor!? Stuff at THAT aisle is more tasteful than what's sold for the V-day).
Thumbprint drawing book was a huge hit with my daughter]
I thought of writing "complete me", but 3-5yo aren't good at V-day humor. The back side of the tag has Kiddo's name.
We even decorated the box.
