I currently have an 11 mo old, 2 one yr olds, 2 - 17 mos olds (some are part time with no more than 4 each day at the moment). There will be a 9 mos old starting in March. I find it okay as I get used to the different personalities and capabilities. However, I will say that for the first bit it was quite a work out keeping up with everything. I bought a six seat stroller so for the really difficult times, we saddle up and hit the trail for an hour. Now everyone has settled in and I find it very enjoyable. I think every provider is different with what they can handle. Infants and toddlers are my niche....I have always preferred working with them and have found that I can adapt well to the ever changing needs. I have talked with other providers who prefer when the kids get past this very needy stage. I will admit that I am asleep before my head hits the pillow most nights though!
