Your 2-year-old now

(from Baby Center my favorite place for finding developmental everythings for your child website)

Your child is more in control of her movements. Now she can play with small objects easily and stack (not just knock over) towers of blocks. She can also concentrate for slightly longer periods of time, as much as 20 minutes if she’s deeply engaged. Sometimes she’ll become so absorbed in playing that she’ll resent your interruption. You can make transitions easier by warning her in advance, as in, “You can play with the blocks for five more minutes, but then it’s dinnertime.” If you have a flexible schedule, you may want to give her a few warnings before you insist that she finish up her play.
