I have four full time children - two girls who are both 2 and a half, and one boy who is 14 months, and my littlest bear who is just 12 months old. It's definitely busy, but I figure in for a penny, in for a pound, right ? Having the right equipment makes all the difference - I have a "super-stroller" and cubbies to contain all the backpacks. I am also able to care for four little ones, because my own three are older - 12, 9 and 4.
