Ds 8 has had stomach pains for over a year. He was finally diagnosed with chronic constipation. He had undergone a disimpaction regime three times to attempt to clear it. We have now been advised to try a dairy and sugar free diet for 6 weeks. I feel so daunted by this and don't know where to begin. It seems that sugar is in everything from bread to meatballs! Do I have to make everything from scratch now? Any advice would be really welcome.
