What do you normally do for your preschooler's class for valentines day? DS1 (who is almost 3) is in a class with mainly 2-2.5 year olds. (His "school" is a daycare that starts calling classes "preschool" once they turn 25 months and has a daily curriculum, etc)

So we were informed that they would be celebrating "Friendship Day" this Friday and we were allowed to bring cards for the day. Parents cannot bring in food as they like to keep food regulated. The teachers would be baking/providing appropriate snacks...

So short of just a valentine's day card for each of the kids (which includes a tattoo), should I make more of an effort and add something else? What are you doing for your pre-schooler's class?
