My daughter is now 4. We restricted til age 2 then did the milk challenge. They said her enzymes were okay enough to have milk. I was very wary at first. She has done fine. Some milk products do cause her to have an upset stomach but for the most part we have seen no issues or problems to report.
These are true stories and messages from moms I have received since I began this journey researching DG in 2008. Sadly I didn't start foldering the messages til 2012 but please see that many are in the same boat as you-confused and with many questions. The post is not to answer these questions specifically but to post to record the issues and questions for the public.
