This doll or a “baby” doll?

My daughter is turning 3 in January and idk if I should get her this doll, or a more “baby” doll. She’s having a ballet themed birthday party, and I figured because she’s tall and advanced that an “older” doll with the possibility of adding accessories would be fun for her. On the other hand she has a new brother on the way and loves playing “baby” with her cabbage patch doll and her teddy bears. She has a baby doll, but it’s one of those plastic ones and not like a soft cuddly one.
