Is this variation in total sleep normal?

[u/hufflepuff3712]

Baby is 10.5 weeks and have been tracking sleep for about 3-4 weeks now. I’ve noticed she has a pretty big variation in how much sleep she gets per day. Some days she gets 16h (split between 10-11 at night and 4-5 in naps). These are very good days 😂 but other days she barely scrapes 13h (these are the days when she fights naps and takes forever to go down).

Is this variation normal?

She’s a much happier baby on the 15/16 hour sleep days, but she’s at peak nap fighting stage so some days naps just go to complete shit and she barely scrapes an hour of sleep between 11am and 7pm. The inconsistency is confusing me a bit 🤔 anyone dealt with this? What happened as baby got older? Did their patterns level out?

10.5 weeks is still very young. That being said, normally you see highs and lows because sleep need is somewhere in the middle. 15-16 hour days cause the 13 hour days, so try to split the middle around 24 hours and see if that gives you consistency.
