Periods of sleep

Do babies go through periods where all the want to do is sleep?

I know in this beginning this is normal but what about as they get older?

My daughter is 5 months and it seems all she wants to do today is sleep.

She fell asleep around midnight last night and slept until about 830am. Had a bottle and a change then went back to sleep until about noon. Had another bottle and change and went to sleep again until 4. Now it’s 640 and she’s fallen asleep again 👀🤔

Wondering if this is normal or if she may be coming down with something
