One of our more favorite educational toys we’ve had the pleasure of reviewing was a gear toy. It’s been in our house now for about 3 weeks, and my daughter still plays with it daily. When it first came in the door my husband got incredibly excited and built things with her. Said it needs a stronger engine so his “cars” could be powered well enough to move on their own. It’s been a great teaching toy, showing her how pieces work together and how things can move. She is more interested in the big pieces and building herself train tracks and towers. I love that she can grow with this toy and it’s not a set age limit, this is something that can grab her attention for years if we allow it.
