Targeting one age group?

[giraffe]

My parent start care with me knowing that they will have to find alternate care when they hit 3 years. They get bored at my house because I am set up for babies and toddlers. If the kids are good and the parents are great I sometimes keep them until they are almost 4. But that doesnt happen very often. ATM I have 3 kids who are 3.5 they will all be done at the end of June, and my new crew of "littles" are starting in July.
