As most of you may know, Ariel is the only one of the Princesses to actually have a child; Melody. This gets me to thinking a very important question: what would happen if all the Disney Princesses had children?
First off, I'm not so sure about Merida right now, as she doesn't have a love interest at the moment, but as for the others, well.....it's somewhat possible for them to have their own kids.
The Disney Princesses stand as role models, mainly for girls, but role models nonetheless. So, with that being said, if all of them became parents, they could be role models for other parents in the world. They could represent the trials and tribulations of being a parent, how being a parent involves making hard choice and not always making the popular decisions. They could show how it's important to set good examples for your kids and make sure that if you had a bad past, that they don't go through the same thing you did and be wiser and more intelligent in the long run. Ariel went through things like this with Melody and the other Princesses would also go through these things and it would be interesting to see how they handle the easy and hard times of parenthood.
