my baby's showing some funny precursurs

[Guest guest]

I need a little advice on precautionary measures to take with my 17 month old ,

little sibling to Levi who's recovering from ASD. She shows no behavioral signs

of autism but has just begun alternating w/ constipation and blow- out diapers,

simultaneous with eczema for the first time in her life and red cheeks, and she

seems whiny, it makes me nervous. What should I do? She is already mostly

gluten/casein and all organic... I'd love some bullet points on steps to take to

reverse the weird gut/skin things.
