I'm a little obsessive when it comes to my shows. Normally reality ones aren't high on my list, but I've been following 16&pregnant since it started.
I've always thought Aliannah and Aleeah were close for twins. I would have preferred something more along the lines of Alana and Aleah. (Though I wouldn't have personally gone for names starting in the same sound). Anna and Leah would have probably been my pick, (If Leah hadn't had the same name!) I think since they call them Gracie and Ali, they could have just called them that in the first place.
Back on track though.
I like Adalyn(n) -Spelt this way-, but Addalynn is not the worst I've seen. The name itself is gorgeous IMO.
