A couple of months ago I was considering only doing 0-2 years because it's usually SUPER hard to enroll 2 yr olds. Most families start them somewhere as babies and keep them there until 3K, or if they have to move them they go to a center so they can "learn something" and be ready for 3K
But I was lucky enough to enroll two 2 year olds this month, and actually had more interviews for 2 year olds or older. But the catch was that most were part time, not full time.
To answer your question, I think it's a good idea. I think that eventually 2K will start being a "thing" and FCC will end up being just infant care. I hope I'm wrong, but that's where things seem to be heading.
