A toddler needs manipulative toys to develop patience and motor control. Blocks to stack, puzzles to fit together, balls to throw and catch, books with pages to turn. Nothing electronic at all.
Hard agree. And a lot of unstructured play. Actually, that should all last well into their pre-teens IMO.
I agree. As they get older there is more room for electronic stuff and it can have benefits. I think the first apps my kids used were things like GCompris.
