Thanks LS great ideas
I will have a look thanks Kelebek.

We are under a pead and dietitian Meow. I have not heard about digestive enzymes, neither have mentioned it. I will ask his pead at our next appt. Thanks for that
His gut won't heal it is from damage done when he had NEC (intestines dying) and bowel perforations.
Fat is important and he does get small amounts and a multi vitamin to try and replace what he does not get and checks on his vitamin levels to see if he is ok.
