I'm one of those crazy caregivers that my best group of children was a group of 5 full time infants who all started within months of each other (just moved and was starting new). I had 5 under the age of 18 months. They grew up together, we're the same age and development that it was the easiest group I've provided care for. But, now I'm a bit older and my back cant handle all the lifting that is required of infant care. Not everyone can work with all age groups and how many infants a caregiver feels s/he can accept is up to the individual. I also have to agree that some infants require more attention than others and the children in care might determine if another infant can be added to the group.

Right now I have the oldest group I've had in a while and they are two 3 1/2 year olds, a 2 1/2 yr old, 2 yr old, and a 20 month old. A part of me is still missing my group of infants, it might have been more physically demanding, but the older children are more mentally demanding and the occasional day I find myself being outwitted by a preschooler, lol.

I'm 3 1/2yrs away from retiring from full time child are and will likely move to before and after school daycare. After almost 20 yrs of child care my back and knees are shot from the years of lifting and being on my knees playing with the children. I'm ready for the older children now.
