I just got my 2 yr old DS a doll, and I am very glad I took him shopping with me. He picked one that I would not. Target's
Bath Baby
I was leaning towards a Rosey Cheeks or something soft like that, but he liked that one. Probably because of the duckies and such that came with. But, he asked for it as soon as we got in the car, and played with it on our long commute home - talking, singing, cuddling. It was very cool.
If his interest keeps up, then I'll probably get him a soft bodied one like a Corelle or Madame Alexander Huggums when the new baby arrives - so he can have a "play baby" and a "gentle baby".
