Baby age and nap schedules

Wondering whose babies are napping on a regular schedule yet? I know lots of us are struggling with naps so I’m hoping I’m not alone in finding my baby’s daytime sleep totally unpredictable!

My baby is 15 weeks and I feel like her naps are still erratic- her bedtime and wake time are pretty regular (7-7:30 pm, 6:30-7:30am) and she usually needs a nap 90 minutes or so after waking, but the rest of the day is all over the place.

Some days she takes five naps, some days three, some days just a few 30 min catnaps... sometimes she is happy for up to 3 hours between naps and sometimes she starts fussing quickly and falls back asleep within an hour.

I’ve read babies start consolidating their day sleep into predictable naps but that hasn’t happened yet... anyone else in the same boat?
