Dear Firecracker 123, can't you find a poor lonely dolly or teddy in a charity shop to keep teddy company when dolly goes home with your GD? That's what I'd do.
I have a family of dolls, some from my childhood, two from my mother's, one of my sister's and I have just got them all into their winter clothes, 17 girls from toddler pre-teens, one baby girl and two little boys.
I've loved most of them all my life (one or two are new additions) why should I stop now, when I finally have time to play with them again?
Then there are the teddies, mine and DHs and an Indian married couple (doll saris are so much easier to sew than dresses!)
