Rated for 3+ but my 2 and 3 yr. olds both play with this. While the kids like playing with this, I like that it can grow with them. It has basic tools for younger children: rolling pin, presser with three tips, pizza cutter, safety scissors, play-doh knife. But it also has tools/items for older ones: bead making, art molds for pictures and "sand".The only con is the mat. It's cheap plastic. Sounded great on the box in the store, but ends up crinkled underneath them and not protecting the floor. Stick with using and old sheet or vinyl table cloth from the $1 store.

They have a little bit bigger size . I ordered a medium shirt for my kid and its a little bit big. I haven't wash it yet if this shrinks it will be perfect for him.

After reading this book, I felt like I was an expert on the how-to's of training retrievers. I have tried out many of these training techniques with my dog and have had fabulous success. And I could swear that my dog has spoken a word or two after several training sessions! I highly recommend this book for anyone interested in having a well-disciplined dog. A brilliant piece of work!
