Hi J.,
Our 11-month-old twins are on Neocate. We fought to get them on it when they were around 2 months old. Yes, we know how expensive it is - but our insurance covers 80%, so that made it a lot easier.
Anyway, I'm not sure what you would need to know about using it that you haven't experienced by now. Mine had a hard time with it at first because it is so thin. We went from mixing Alimentum at a higher calorie level (so even thicker than typical) to the Neocate, which is like water. They had reflux quite badly before the Neocate but the Neocate made it worse because it was so thin. To ease the transition, we slowly mixed small amounts of Neocate in with the previous formula. That helped the reflux a bit, but never eliminated it.
So, that would be the only thing about the Neocate that I think you would need to deal with for your baby.
Oh - warning - Neocate smells horrible going in and even worse coming out! I honestly can't describe the Neocate odor - but you may already be experiencing it, so you could know what I mean. And, poops generally turn a blackish green on Neocate along with the amazing stench. That's because it is so broken down already that the bowels just don't have much work to do. Ok, that really is all I can think of.
Feel free to contact me if you have any Neocate or MSPI questions. I'm not a pro, but I've been going through it with my babies for almost a year now.
Best,
L.
