Most kids love to imitate. Sit down and clap your hands. Pat your head. Encourage her to imitate you. Change the motion quickly and see if she will follow.
Stand on one leg.
Pat your tummy
wiggle your nose
shake your hands or head
etc!
Here is another one we did with the 3-5 yr olds.
Teddy bear, teddy bear,
Turn around.(turn around)
Teddy bear, teddy bear,
Touch the ground.(touch the ground)
Teddy bear, teddy bear,
Go upstairs.(walk up the stairs)
Teddy bear, teddy bear,
Say your prayers.(hands folded in prayer)
Teddy bear, teddy bear,
Turn out the light.(pull light chain)
Teddy bear, teddy bear,
Say good night.
And one more Jack in the Box
Crouch down on your heels with the child imitating you
Say: Jack in the Box Jack in the box Jack in the Box
(Repeat as often as you want) Jack out of the box!(jump up)
Kids love this one.
