C3 1 adult and 1 helper gives you max 2 under age 2 (1 max infant....8 preschoolers...4 SA)
Does that help? I always have such a hard time with the ratios so I have a little chart with stick figures all drawn out so I can see it, rather than read it. 
Are you sure on that? Because isn't a c-1 with 3 under 2 with no more than 2 infant? I dropped down to a c-1 because I had a 22 month, 5 month and 3 month and was told I didn't need a second adult.
