It's a mystery to me why GP's and/or hospitals don't look at diet earlier in the pregnancy. The only booklet I received mentions eating more carbohydrates and more fruit and veges, when this is not necessarily the right diet for everyone.

When I went to the ABA breastfeeding class, the lady there also gave us a handout about new research to do with the mother's diet and colic. It mentions that it is better to eat a lot of good fats, rather than eating more carbs and fruit.
