My daughter loved playing with wooden blocks building them up and knocking them down. She especially loved knocking down the towers that I made. She knew all the different shape blocks and how to put them together to build taller and taller stacks as the weeks went on. She had a large set of the Megablocks and loved stacking them up and creating things with the same color shapes and then same sized blocks. She loved to organize them afterwards by the color and shape.
My cousin bought her a set of Super Hero Duplos.
She loved playing with Joker and Batman and really liked to play with Batmobile that came with the set.
