Oh Lammily...
My issue with Lammily is that the creators obviously had good intentions regarding promoting body image etc, but they've created a toy which perpetuates gender stereotypes. Lammily may have a more realistic body, but ultimately she just a dress up doll; she doesn't DO anything. Only boys get to play with action toys. Girls have Barbie or spotty chunky Barbie. Neither can pose well at all.
Little girls don't learn about body image from dolls, they learn it from the women in their lives and, unfortunately, from films and so on. No little girl thinks she's supposed to look like Barbie, but she probably does think she's supposed to look like Katy Perry. It's not an issue with toys, but gender stereotyping really is.
