Hi Karla,
I have a daughter who is now almost 22 months old. About 6 or so months ago, she started to get interest in "playing" (more like, dragging around) with a porcelain doll I have had for years, that I have had standing on my living room carpet in her doll stand! It wasn't an expensive one, I just got her because I liked her face and auburn ringlets. Her hair was so pretty and the ringlets were soft and perfect, but now the hair is a total mess of frizz....you can still see the ringlets, but they are pretty frizzy!
I'm not sure if your granddaughter would even be interested in your dolls yet, being that she is barely one year old. Is she walking or active yet? I don't think my daughter bothered with that doll quite yet at 12 months, but your granddaughter could be different. I guess it depends on how expensive your dolls are. I assume they are standing on carpet like mine? If yes, then the porcelain probably wouldn't break if they tipped over. But like what happened to mine, the hair became a mess. Of course, that was after my daughter had dragged her around and held her numerous times. Now that the doll is a mess, she hardly bothers with it! Good luck and enjoy your visit with her!
