DD is 5 and an only. Over the last few months she has mentioned a "sister" who she pushes on her swing. Today she mentioned a "brother".
I've managed to get bits of information here and there, and it turns out the whole thing was started by her grandfather. The fact that it was his idea is a whole different conversation as there's an agenda there that needs sorting out.
My problem is I really don't know how to react when she starts talking about it. TBH I'm uncomfortable with it - partly because it was the grandfather's idea; partly because it makes me think she really wants siblings; partly because I'm afraid if it continues she'll isolate herself at school.
Is all that crazy? If it's a healthy part of growing up, I will let her carry on. So far I've just made comments like "Oh, that's nice" and not encouraged it at all because I feel so uncomfortable with it.
Sorry this has turned out so long! Any advice or experiences shared will be greatly appreciated.
