I think that if you are thinking about selling your collection, you should do if very gradually. First I would pick one or two dolls that you want to sell and only sell their outfits and accessories slowly. This way if you change your mind about any of them, you have only sold a few items that could easily be replaced. After you've sold some clothing and accessories reevaluate how you feel about selling parts of your collection. If you still feel like you want to do it, I would continue selling slowly. This way if you have any regrets, you would not have sold anything major. I would do it this way because it sounds like you are having some doubts. Also, I feel like I have to mention how luck you are that your mom supports your collecting. I am 24 and my mom thinks that I am too told to collect dolls (although she does think AG has beautiful doll... but for chldren!). I just got my 5th AG and I am wishing now that I had limited my collection to just 2 or 3 dolls. But I am now way too attatched to them to sell any of them! Good luck with whatever you decide to do.
