Ds2 is 19 weeks old and ebf. He developed eczema a couple weeks ago and we were prescribed Cetraben for it. That didn't work so we've been using Aveeno on it. He has also had the most vile nappies for about the same amount of time - green, runny, frothy and mucousy. Last night we had a dreadful night - he vomited his second feed around 3am, then would only go to sleep in our arms. It has been the same since then without the vomiting. Every feed he finishes crying, he is exhausted but won't sleep or at least keeps waking every 20 or so minutes. When he is awake he's crying or moaning and really not himself. Any ideas if it's a bug, or something else? Or both? And what should I do? Ds1 has a very robust constitution and never had anything like this!
