Hi, I'm hmmm, (well lets not go there) but lets say I am playing with dolls since I don't have any Grandchildren. I am on the 3 year plan before I get any. And if I am lucky and God is smiling down on me I will get a Grand daughter in 3 years. I don't think you can be too old to play with dolls. I guess it would depend on the amount of time you put in to them as to if it could become unhealthy. So get them all dressed up for Thanksgiving. Enjoy!!
