Your child is learning about numbers all on her own. You can find out how much progress she is making and even help her along.
Take three objects
Count them into a box while your child is watching.
Take the box out of her sight for a minute.
Take one of the items out.
Bring the box back.
Take the two objects out of the box with her.
See if she looks for the third.
Infants of one and over will generally be surprised not to see the third object, proving that the can count. If she is surprised, try the same trick with four or five objects to find out how far her counting goes. During the year she will probably get better at knowing how many objects were there.
