Children notice what is going on around them. They see the decorations, the cards, the flowers and candy; and, they want to be a part of it. It isn't the holiday that should present any issues; it's the way it is presented.
When I discuss Valentine's Day, I tell the children I get excited to let the people I love know how much they mean to me. I make sure that we also talk about how you should let people you love know as often as you can; it's just that this day is set aside for especially doing that.
Then, we sing this song..........
after which, we discuss, "Who was given Valentines in this song?", "Who would you give a Valentine to?" (You can use this opportunity to graph people's answers.) After that, we make Valentines.
Here's a simple pop-up card to make.
