Jigsaws and dinosaurs

Louka used not to "get" jigsaws. She had some fairly simple ones, but always needed me to do them for her. Then one day, after not even looking at them for weeks, she did them all by herself. I was so impressed that, when I saw this puzzle at the museum, I bought it. It's intended for 3 – 5 year olds, so I thought it would be pretty challenging. But she got it all out, first try, with very little help.
