LO is a notoriously awful napper -- unpredictable lengths, takes some effort to get him to go down, but doesn't do well without naps, either. It's improved some with age, but still isn't great. And at daycare, it's even worse. In his room, which is infants 6 weeks - 6 months-ish (though he's the youngest), they do lights out from 12-2 but otherwise nap him on demand. They do their best, and are really good about doing what they need to do to help him sleep, especially when he's clearly tired. But he often logs only 1.5-2 hours total throughout the day. Now that he's going through a 4-month growth spurt and is up 4+ times a night, he's just not getting a ton of sleep and has screamed in his car seat the whole way home this week.
I know some of this is just growth spurt stuff, but I am thinking that getting him on some sort of a schedule at home, timewise, might help at daycare. So far we've just been doing an hour to an hour and a half of wake time, but I think that's hard for daycare to follow, hard for him to get used to because it puts his wake and down times all over the place, and hard for our schedule in general. You can't really plan your day when you don't know when your kid is going to be going down for a nap.
Is 4 months too young for something like this? And if not, what kind of a schedule (2-3-4, specific times, etc) was your baby on at this age, whether led by you or a natural rhythm they fell into themselves? Because he's totally not falling into a rhythm himself
