Jerilyn sees the light

Jerilyn has been playing with blocks for months but only recently she seems to understand the rule of the game. She used to just use all her might to push the shapes into the holes but now, she can identify the shapes for each hole. Not only that. She also play stacko and remove 1 by 1 like an adult. I feel that the cause of this sudden development is because she saw how her cousins play with mahjong: stacking them into pyramids and other shapes. When she comes homes, she does the same with everything, from her toy blocks to my dad's tins.
