I introduce you the Lammily dolls -- created by Nickolay Lamm. These dolls have been on the market since November 2014. The primary goal for Lammily was to create a doll with "typical" human body proportions. You can also get the sticker-expansion pack for the doll to add other things like cellulite, bruises, and scars.
The new "Period Party" pack comes with an educational pamphlet, 1 pair of panties for the Lammilly doll, 18 reusable pads and liner stickers, 1 calendar, and dot stickers to track periods.
The doll is meant to open a dialogue and teach young girls about the bloody, monthly mess.
"I've read horror stories of kids thinking that they were dying during their first period. Parents are also wary of approaching this subject," Lamm said. "So I feel Lammily's 'Period Party' can introduce kids to menstruation in a very fun and disarming way, and give parents a very useful tool." (Mashable)
I think this might be as bizarre as some of the baby dolls that can defecate, but I think there's something actually useful here -- a doll that can actually teach young girls about their menstrual cycles. And maybe make it easier for both parents and daughters to have a conversation about "da period talk" and some of the issues around it.
