Our 12 year old daughter is the youngest of 3 (2 brothers up and out) and the only girl on both sides. Problem is she has a lot of dolls, doll accessories, art supplies, etc. that have accumulated over the years and we are tired of looking at them in the family room, even though they're organized. She has a small bedroom and we don't have a basement. Is 12 a good age to suggest giving some items away and boxing some up (like we did when she was younger)? She's a good kid--but when is a good time to confine most of her toys, etc. in her own room? Thanks.
