some movie theatres do have mums & bubs sessions, I dont know if they would be showing twilight at any of them though! I think the main thing to be not worried about, but I guess aware of, is how other movie-goers are going to react if she starts crying..as long as she is quiet I doubt anyone would know she was there, but I know that (even though I do now have a baby) I might be a little annoyed if I was trying to watch a movie, especially as Twilight is quite popular, and there was a baby crying...

I know babies cry and most people understand that, but I guess its just something to be aware of. I say go for it though, will be a good time out for you and your partner
