My sister is a midwife in QLD and she said its something one of her Obs does quite a lot up there and it has worked really well as hardly any of there mums end up having to be on insulin. It is something I discussed with my Dr's in NSW but apparently there hasn't been a lot of study done into it. I guess different dr's have their own way of doing things - I certainly would of tried it if I had of been given the opportunity.
