Well, I have 14 dolls. They currently live with my parents, since my apartment would NEVER fit them all. But first, I must say, I miss them terribly. And, since I was little and started collecting, it has never occured to me to collect quickly or to play with them all at the same time. I understand your desire to spend more time with the dolls you feel closer to, but I think that you'd probably regret selling your dolls. Maybe you would consider using the dolls you don't really feel are special as display dolls, or if your mother really loves them, you can use them and their accessories as gifts for her! Get her into collecting, and then, not only will you not regret losing your dolls, but you'll be giving them a good home, as well as creating something you and your mom can do together! That's just my thoughts.
