Dear T.,
I don't have a brand or anything to recommend, just features.
At 15 months, her doll should not have real hair, only molded.
It should not have opening and shutting eyes.
The body should be cloth, and it shouldn't be bigger than she can carry.
If it makes noise, it will wear you out!
The eyes should be open, kids don't bond to dolls with closed
eyes. If the arms, legs and head are plastic, that's probably okay, but the body should be cloth at least.
I wouldn't get her anything bigger than 15 inches at this time.
So, there you go.... My daughter loved hers, carried it everywhere, but alas, we did lose her, so maybe get 2 identical dolls to have a spare..... Best of luck. B in Plymouth, MN.
