Light up Legos

Here is Esther playing with Van's light up legos. (Van is picking out his bedtime story in the background). You can see how they work, if you get them plugged into that purple triangle, and then press the red button your building will light up.
I love watching her play with these because she's very deliberate. You can tell she has a plan. She'll often sort by shape and put and build symmetrical statues. Or use just one shape and make it as tall as possible. It looks like she's running experiments, checking through all the possible options of how it could be done.

"There." she says when she's done.

"look. look. Look, mama" she says in this one.
