It's hard for parents to catch a break during naptime when they have an infant taking two naps a day and an older child taking one, but stick to their schedules as much as you can. I tried to do this when I had child care in my house and I was working from home. But on the days I didn't, I should have arranged for one of Hannah's preschool classmate's parents to bring her home in the afternoon while her brothers were napping.
When all of your kids are on one nap a day, keep to a routine of giving them lunch together and then putting them all to sleep. If one goes to sleep more easily, put her in first so you don't miss that window on the child who may be more of a challenge to get to sleep, Dr. Kass says.
