My 2 month old puppy is not playful at all we try to play with her. All she does is eat and sleep

She is only 8 weeks old give her some time. She's a wee baby.

Think of your fur babe as a 2 month old human baby. All they really do is eat and sleep too! Give her time to bond with you. She is also probably missing her momma and the litter. Don't get anxious, she will start playing with you when she feels safe.

Is she eating well? When she is awake does she seem alert and interested in her surroundings? Has she been dewormed?
Parasites and low blood sugar (especially common in small breeds) can zap a puppy's strength and cause excessive sleeping.
If all these bases have been covered, I agree with the folks above--the puppy is a little overwhelmed by all the new things and she should come around to normal activity before long.

If she's healthy and calm, I wouldn't purposely try to rile her up unless you want to end up with an overexcited mutt.
