Audrey, when I paint toddlers, I tend you use less layers then I do when painting newborn. You still want all the detailing, but just not as thin skin as a newborn would have. I made a free tutorial in the tut section on painting Angelica in as few layers as possible.
I also have a pretty in depth toddler E book that goes into much more detail on painting and assembling toddlers.It is 144 pages with full instructions and pictures. It is $20.
Hope that helps!
