Starting Early

I am thinking of starting this GAPS meal plan early.  My poor 5 yr old boy is having a rough time with his tummy.  He has been having diarrhea every morning since last Monday which of course was the first day of school.  We don't know if he was fed at school or just a little nervous.  We finally had a good morning today and no diarrhea which I was a little surprised because he went to bed last night with out eating because his stomach was so sore.  This morning tho he woke up fine and had breakfast and had no issues with his stomach.  Hopefully the diarrhea is over.  Now to convince the family that we might start a week early.  Hopefully this will go well.
