2mo old sleeping a lot

Ranae

My lo is a little over 2 months old and has slept for going on a total of 13hrs over night with only waking up once to eat. He is currently still sleeping. Is this normal? The other night he slept for 10 straight hours and the night before that 8.5. I don't want to wake him if he's that sleepy but I'm also worried that he's sleeping so long!
