We're almost 3 weeks in and my son is actually letting me feed him without a fight now. It's been a horrible few weeks but we're getting there!

Personally, I'm finding the carb cravings constant. I just want some toast for breakfast! I need to make more of the GAPS things like nut crackers and bread.

A couple of things I forgot to say before...
Keike- you wont detox just by cutting out sugar so don't worry about going through detox that you can't handle. The book explains how to slow down detoxing so you don't overload your body by releasing too many toxins too quickly. The main ways to detox are by adding in probiotics and drinking fresh vegetable juices. I'll most likely skip the juicing while I'm BFing.
The carb cravings are another matter though and it can be a little tough but not nearly as bad as I thought. And I honestly was a MAJOR sugar/carb addict.

Tashybabe- It would obviously be best/easiest if your H did GAPS too but plenty of people do it alone and it wont stop your healing if your H doesn't do it. If you develop a good gut flora you will be able to fight off his bad bacteria (introduced to you during sex) and your children will mostly get your flora so they would be fine too.
