There is no really age appropriate hair for infants. Poser World has some baby hair, but it looks more toddlerish to me than "baby".

If your computer can handle it, maybe try the hair room?  Or paint some peach fuzz on in post work.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
