I have a DD and expecting Dc2. We don't know the sex but everyone we talk to says how we might be lucky and have one of each. Why is one of each the holy grail? I would be thrilled if we have two girls. Plus I think siblings of the same sex would be nice (not that i think opposite sex siblings wouldn't get on). I would equally be thrilled if we had a boy - something different, a father/son relationship for DH etc. Either way is nice I think.
I don't know what to say to people when I say we don't mind either way and they look at me like they don't believe me.
