I have an 18 month old and have been using the same baby seat since birth.

The only problem I see is they have changed the design since I purchased it. If you can go to the store and find the one w/ the little yellow toy in the middle, I would recommend buying it at the store. If it does not have the toy, I'm not sure how good it is.
