Work out a schedule that fits your lifestyle. Be willing to be flexible with it when you need to be. I have 3 kids - a 1 yo a 4 yo and a 5 yo. I'm a WAHM (P/T) and the 4 and 5 yr olds are in school M-F till 3 pm. Our schedule is:
Baby wakes up 7 am, change diaper and clothes, eat breakfast and have a bottle. Play a little while we get the big kids ready for school.
5 yo on the bus at 8.
4 yo walks to pre-k, which starts at 8:45. Baby goes in his stroller, we take a pleasant walk there and home by 9, he goes down for his nap. Naps till between 11 and 12. (This varies depending on if he poops while he sleeps, which will wake him up).
Change diaper, eat lunch, playtime, sometimes runs errands with me.
2:30 walk to the 4 yo's pre-K, pick her up. (Has a snack and a 2nd bottle here).
Home by 3, 5 yo off the bus.
Nap #2 is a one hour from 3 -4.
Wakes up, change, playtime then dinner by 6.
Then a bath and into pjs and a 3rd and final bottle at 7 and into bed between 7 and 7:30.
We're flexible on the weekends if we're going out somewhere.
We're flexible about nap #2 if I'm taking the girls somewhere.
I try and stick to the morning nap as much as possible. M-F that's when I work.
This is what works for us. Having a schedule and sticking to it without killing myself over it has worked really well for our family. I have 3 great sleepers. No kids in my bed and no nighttime drama.
Good luck!
