I am mom to 4. I started care when my first two were almost 2 yrs and the other 4 months. I always had my quota of 5 others. Nine was normal to me and never considered it a problem. I rarely had more than 2 under a year be it mine or others but the rest were whatever was available and I tried to have one for each age that mine were so they had a buddy. Anyone who has seen shows such as 19 kids and counting sees the difference in running a tight but loving ship vice the out of control Jon and Kate gang. It isn't so much the kids that is the issue as much as it is the caregiver and not taking on more than they can handle. Just because you can have 5 extra or have 5 toddlers doesn't mean you should. Then again it was so much easier back when my kids were little because the kids I had in care from homes where rules were enforced and expectations and respect expected and that made a huge difference in my ability to get cooperation at daycare.
