Hello Jaz, welcome to this wonderful group of people. I'm pretty new here too and like you am assisting my husband who is in very early stages of AS. We started doing the nsd diet 10 weeks ago and just recently also eliminated dairy.
I've found that you have to be quite dedicated and it does take more time. But getting your son used to it at his young age will be very beneficial.
Stay in touch. This forum has helped me immensely and we don't feel so alone.
Best wishes to you and your family
Jude
