One of my three year old granddaughters likes this box of seventeen infantino puzzles found in the Costco book section. The direct quote from my daughter was "a big hit."
As far as I can tell by looking on the Internet, the price was great.
Of the two Costco infantino sets that I saw, one was for ages 1-3 and one for 3-6. I bought 3-6 although she's only a little older than three.
This child is a puzzle fan and these puzzles didn't look too difficult to me.
