Every toddler is an active learner.
With his new found ability to walk around, he's in a whole new relationship with the world and can explore new territory like an old world adventurer. Through his falls, his bumps, as well as his triumphs and discoveries, he's learning about how the world works and also about how his own emerging self can help it work even better. Provide him with lots of concrete learning materials, things he can pick up, roll, punch, stack, squeeze, bounce, pound, push, pull and in other ways, interact with. They don't need to be brightly colored fancy educational toys. While much of his behavior may seem haphazard to you, there's actually a lot of intelligence going on in even the simplest of acts.
