It's distressing & exhausting when you have a colicky baby so just by changing a few eating habits may help the microbiotic imbalance in your baby. The most irritant foods in your diet would be: dairy, gluten, sugar, peanuts, shellfish. For a short time try and cut down on these foods and try and eat more probiotic foods or even good quality supplements (NOT cheap ones!). The latest thing to try is Sauerkraut - can even get this at the supermarkets. Its only for a short term relief and is worth it if your baby stops crying!
