It's also hard when one book, one author or one website (not this one!) decides there is ONE way to go and stubbornly sticks to it. Follow the rules and you will get this outcome.....just follow the RULES.

As adults we would not insist on making ourselves go to sleep with a tummy ache, so why do some people think we should do it to our babies?
