"Congratulations" is the last word I'd use in this kind of situation. It's going to be tough for Ms. Dunn to juggle motherhood AND making it in the fickle fashion industry. Add that to her young age and it's a recipe for disaster. I don't care if so-and-so-model made it work - it is an enormously difficult challenge to be a mother at such a young age, when you yourself are just beginning to understand and create your identity, and figure out what you want and what you want to do in life. Best of luck to her in navigating her journey.
