Bought this body for my 5 yr old preschooler. Its a great intro to anatomy and gives great opportunity for us to talk about how the body works. It is sometimes hard for her to snap the bones into the "skin" and sometimes hard to snap the front and back together, but this was made for older children. It comes with a book that explains what happens to your food once it enters your body - though we haven't used the book much. The organs are squishy, will break if played with too roughly (my 2 yr old ran away with the intestines and broke them before I could retrieve them). Luckily we just smooshed them back in place!  What surprised me was when my little one started asking to play with it - I initially thought it would only be a "mommy-initiated" activity. Turned out to be a pretty cool Christmas gift after all. Word of caution if your child is younger - I do not let my child play with this unsupervised because of the small pieces.
