In our home, we love toys and games that promote learning. So, we have all of the usual "building block" toys. All of the children love them, but eventually they get burned out. There are only so many times you can build the same set, and the sets get expensive. This is why I LOVELaser Pegs! Their sets do not just build one model, but are meant to build multiple items. So, once the kiddo finishes the first combination, they have more to go! The best part ofLaser Pegs, they light up!! My kids love to build them and then play in the dark. It brings a totally new perspective to their playtime.
