Even though I haven't been the best example of a baby wearing momma, Jaina seems to know instinctively that her dolls and stuffed animals would much rather be carried next to her than in their Graco babydoll carseat. Because what is a carseat for? To ride in the car, of course! There's no danger of one of HER babies developing plagiocephaly!
This back carrier (that can also be worn as a front carrier, kinda like a mei tai), was made for me by my mom when I was four or five years old.
