sleep schedules

Jenna
My 5 month old is sleeping from 7:30pm/9pm - 7am ish ( though waking up several times at night to feed or be soothed). Her naps are all over the place. Partly because she goes to daycare 3 days a week. And I have a hard time getting her to sleep without nursing when she's with me. She also refuses the bottle (which is another story), so it's making getting a nap schedule hard since I'm not always there to feed her. I don't mind that much, but I'm wondering if it's not good for her. Do you other moms have a good nap schedule? And if so, did you work hard to get the schedule or did your baby also naturally find one on they own with a little help. I'm also against cio. Some days she will only take 2-3 naps that last 15-40 min, which means she's up 3-4 hours sometimes, which seems like a lot for a 5 month old. Thanks in advance!
