I'm trying this second time around to have less light up, battery powered toys. My older son went to a Montessori preschool and loved it. I'm hoping to start a little earlier with this one with a similar approach. I'm not capable of going all out in terms of setting up a Montessori playroom, but would like to incorporate it as much as possible. Anyone doing this? Any favorite toys/items for the next 6 months. He's starting to crawl and explore and is less interested in the smaller baby toys he's been playing with.
