I bought this for my grandson's 1st Easter. It was the Easter Basket as he was only a few months old. He is now 19 months. He learned to walk with it. He "helps" out around the yard with it. He also uses it as a toybox for stuffed animals that he occasionally gives a ride too..
My 11.5 mos daughter loves her little red wagon. It is very sturdy. She likes to practice walking forwards and backwards. She also likes to put things in it and push them around. Her 4 yr old cousin sat in it and she pushed him around. We aren't using the side rails right now but them seem well built, as well. So far, we're not having any problems with pegs that slow the wheels (others have said they break off). I plan to remove them as soon as she is able to walk on her own. I would recommend this product! I will buy other products from radion flyer.
