Before I had kids I would have thought you were crazy if you told me I would have an entire bin just for Valentine decorations. Somehow it seems less like work when you see the kids faces light up when they see the new decorations. I try to keep things simple. New dining room table decor is a must, swap out the christmas wreath for a heart. A few touches here and there a blanket, window clings. I changed out the Christmas ornaments in a few centerpieces so that only the red and silver balls are out. It took me half an hour. Every room has a little something and instead of being sad that the Christmas decorations are gone the kids are over the moon about Valentines Day!
