4 and a half month old DS has suspected cmpa. I say suspected as we've yet to see a paediatrician for a formal diagnosis, although GP is confident this is the issue.
Background is that he started on sma formula (I was unable to breastfeed) and always had slightly dry skin. When he was 2 months old he started getting very dry, sore patches on his knees, elbows and shoulders. He was always very irritable, crying more than normal and had started to have diarrhea twice a day. GP prescribed Aptamil pepti. DS wouldn't take it, even mixing it with sma, and 4 days in was dehydrated so we went back to sma. GP said to try the soya sma. We did but his skin worsened, so GP prescribed nutramigen. DS was 3 months at this point. He took the nutramigen fine but his skin worsened again and was cracked and bleeding in places. He also had diarrhea 6-10 times a day. GP was reluctant to change formula again as nutramigen works for "most" babies. She put in a referral to see a pediatrician and a dermatologist at the children's hospital. In the meantime DS skin is dry and cracked in most places on his body, the bleeding bits are on his chin and neck and elbows.
An out of hours doctor recommended neocate formula so I went back to my GP and asked for it. She was very reluctant but prescribed 4 tins in the end. Has only been on a full bottle of it for 2 days so obviously I have no idea if it's helping yet. He is still having diarrhea 6 times a day at least. (His stools have been sampled but there's no underlying infection or anything).
I also got an appointment for a peadiatrician through for the end of this month. The dermatology department then called with a cancellation so my appointment for them is this week.
This bring me to now. The past few days DS has been miserable. The skin on his face is so dry and broken, it's bleeding and weepy and he just wants to scratch at it all the time. The minute he is undressed he just grabs at his chest and legs and screams. He's been sleeping about 8 hours in a 24 hour period for the past 3 days. GP wants me to hang in there until my appointment but I honestly don't know if I can take another night of this. The dermatologist isn't exactly going to wave a magic wand and make him better, plus I still need to wait to see the paediatrician. I just want someone to see DS and assess him properly.
Should add we've had zerobase, epaderm, hydromol and zeroderm moisturisers. None of them have worked. Hydromol and oilatum for the bath. Also had hydrocortisone, eumovate and fucidin for the sore patches but again they've not worked.
I'm just at my wits end and wondering if taking him to A&E is worth a shot 
Has anyone dealt with this with their babies? What would you do if you were me?
