4 days till my planned section and I've found out that my sister, due in 4 MONTHS has picked the same boys name as us. Thinking that she was a reasonable human and wouldn't use it, I told her that was the name we have for a boy. (we don't know what we are having) but she says she isn't bothered she is going to use it anyway! We are from a small family; just me and her as siblings and I've pointed out how ridiculous this is but she doesn't care. Now I'm really really upset, don't know what to do, I don't want my baby to have the same name as its cousin and yet we don't have another boy name and I have 4 days!!
