Yes u can. U can have 20 kids enrolled. But just never go over 5. Because u have 2 under 2 u have to count ur 4yr old. But once that 21mth old turns two u don't have to count ur 4yr old during the school yr. if u stay at 2 under 2 then ur 4 yr old counts but if u only have one under two then u don't have to count ur 4yr old during the school yr including march break, Christmas break and pd days. But will count in the summer
