Good for you Airline and DH - sounds like you have a plan (and a supportive DH which helps exponentially). Yeah, it really sounds like a cows milk allergy/intolerance with the formula poor little thing, hopefully what you're doing will do the trick with the EBM, it's all a learning process, all you can do is try different things, some things will work and some things won't. It's all part of the process and hopefully you'll see some steady gains soon. All the best.
