Too much sleep?

So on tuesday DS didn't sleep at all during the day and was very fussy. He slept through the night like usual. Yesterday he went back to his normal 1-2 hr naps twice a day and slept through the night once again. Today he's been sleeping all day, only waking up to eat every 2hrs or so. Is it normal for his sleep to fluctuate like that? Is there a such thing as too much sleep? I'm afraid that since he's slept all day he won't sleep at all tonight.

Probably a growth spurt. How old is he?

He's 9 weeks

Yeah growth spurt. He's fine let him sleep.

Thats normal sometimes my son slept all day and night then he would be up all day and still sleep at night.

its normal
