Yes, I usually get them a small toy.
However, in the past I've given them blankets, blocks, a Nerf gun, cute pillow for dtr's room, a rug for their room, a ball, picture for their room, book, pens/finger paints, stickers, craft supples, doll, Matchbox cars, puzzles or a board game etc.
I decorate the house w/red, pink & white streamers & balloons, lights.
Make fun food (heart shaped pancakes in the morning, I use one of those metal cookie cutters for cutting heart shaped toast or to cut out their sandwich once it's made, I buy heart shaped crackers, make a heart shaped cake.),
They get them some candy.
I give them those little cards you buy in a pack for them to gake to school.
The older ones take those to school.
I set the table w/heart shaped plates. Just little fun things.
