sleeping ALOT

my daughter has a cold and an ear infection, she is on medication for the ear infection and her doctor told us to give her Tylenol through the day as well and she's sleeping A LOT!!! She slept from 9:30 PM till 7 AM, my grandma took her downstairs for a bottle and to play with toys, she was only up for about an hour and went back to sleep till 11:40, and I had to basically force her to stay away till 12:45 and she's been sleeping since then (it's now 2:20). is it normal because of all the medication??
