I have two one year olds, and 2 two year olds, and one three year old.
My one year olds both nap from 9:30 - 11:30, and again from 2:30-3:30. My toddlers nap from 12:30 - 2:30. I dont get any alone time, but this allows me to work on appropriate skills with my infants, while still doing appropriate lesson plans for my toddlers.

Outside time is the end of the day, assuming the weather is nice. Sometimes, we will have outside time before lunch, but this would be out on the deck that is fenced in where I can leave the kitchen door open and keep track of the kiddo's. We have a slide, and a sand and water table and a picnic table, and a climber set up out there for the times when I can't make it into the yard.

Some infants still need naps... I actually worked them into their nap times, because I was finding it to difficult to work individually with each child when they all were all up at the same time. And obviously infants have different mile stones to hit, than toddlers. So this works well for me! The infants and toddlers have breakfast and circle time together. Then the infants go for their nap and we do craft and practice our writing our letter and numbers. etc...
