So, for a long time my daughter would only sleep for 37 minutes at a time.
At around 7 months, we got that all ironed out. She sleeps 10.5-11 hours at night, and then has two naps, usually for 1-1.5 hours.
I log her sleep on an app and pay attention to how long it takes her to fall asleep when I put her down. When she stays awake and plays for awhile before going to sleep, I push her awake time. If she acts tired before the normal time, I put her down early (though she rarely does). Using this method has helped us get pretty good naps.
But her awake time is already at 3 hours 50 minutes!! It's getting hard to squeeze in the second nap, especially if she sleeps 12 hours like she did last night. She woke at 7:20 and napped from 11:10-12:30. Now I don't know how to get another nap in before bed. I suppose I can let her take a very short catnap at 4:20 but I worry that will mess up night sleep. Her 7:30 bed time is pretty locked in at this point.
She's happy and mobile and doesn't act tired. 9.5 months seems so early to go to one nap, though!
