Ooh Annie and MrsBadger, I mentioned dunstan baby language a week or so ago, we love it! James says a very clear "Neh" when he's hungry, which helps immensely. He only has to mutter "neh" in the night and I sit up and feed him, no screaming necessary!
He also says "aah" when he says wind, I'm not sure if that's the exact word dunstan baby language uses but James always uses it when I haven't winded him, then I wind him and he does a huge burp!
He doesn't seem to have a particular cry for anything else, he seems quite happy to sit in a wet or dirty nappy, so I've had to get into the habit of changing him after feeds, or every three or four hours just in case!
He's a good boy though, doesn't cry unnecessarily, it's only ever food, wind, dummy, cuddle!
I don't blame you for sleeping wih Nell, Annie. It's so nice sleeping next to them, you both sleep better and longer. They say that in countries where babies always cosleep with their mothers, there's no such thing as SIDS. All I know is it makes us happy (and drives dp mad!)
