Thank you both Murphy & Jess.
Murphy- I love the idea of solidarity and started thinking about it this way... It's good that they both have it because if FPIES really is 1 in 10,000 than Marcus will never meet anyone w/ it and feel alone. But if Tommy has it too, than at least they will have each other? Sort of backwards but w/o finding some sort of silver lining, I would go crazy.
Jess- After 4 other formulas, it seems as though Thomas is doing okay w/ Neocate Jr. Simultaneously Marcus is not wanting to drink his elecare but has ZERO interest in the taste of Neocate. Going to have to trial some of the tastier options I guess.
