Sleep schedule?

The last 2 days all my son really has done is sleep. He is 2 months old. Is this normal? He got up at 7:30AM to eat went to sleep got up at 11:40AM and then he slept till 5:30pm. He eats bout 5-7 oz and we put a tablespoon of cereal in it to thicken it up because he kept spitting up a lot. Is it normal for him to still be sleeping all day?
