Seems as though I have one of the smaller groups. My own two monkeys, a daughter 3.5 years old and my son who turned 2 at the end of December. I also have another 3.5 year old little girl (who is leaving the end of June - she'll be starting an all day kindergarten program and I will be looking to fill her spot) and a little guy who just turned 2 at the end of March. They both come full time from about 8am until 4:40pm Monday to Friday. All in all a pretty good group on most days I have said from the beginning that I will never have more than 4 kids in my care at one time. 4 just seems to be my comfort level for now.
