As much as I dislike some forms of sleep training I am a big believer that if they are to be done they should be done in a supervised situation like a sleep school so things like this do not happen.
Hun Torrens House is a sleep school.

One of the lovely ladies on here took her DD to sleep school before she was 2, and they tried to make her wean and all sorts of other things against the WHO code. It is disgusting what these places do. They should be encouraging mothers, not telling they are doing everything wrong.
