Do you still have the documents the tablet came with? if you do recheck and see if you paid for warranty or if it came with a warranty automatically. You didn't say how the screen broke, if it came so or your child broke it. Most warranty covers manufacture defect, so you would also have to check when looking for the warranty what it covers and for how long (make sure it hasn't expire) If you bought the tablet online it might be easier to locate the information, simply go to the site and check your purchase history.
