"Shut Up And Go To Sleep!"

Lastnight when we put the girls to sleep, Natalie just cried. She always cries when we put her to sleep. I mean she's nearly two years old and she still has to cry (Vanessa has grown out of that stage long ago). Anyways, usually Natalie cries for the first 10-20 seconds and then she's quiet after that. Lastnight she was going for five minutes or so. Fiona was listening in and she heard Vanessa baby talk something to Natalie and then she stopped crying. My guess was " Shut up and go to sleep!" There were few other incidents where I'd hear Vanessa saying to Natalie "Nigh' nigh'!" (but I don't think that was stern enough).
