Slippery Elm shouldnt be the cause of the eczema so ya know..... Id be very surprised... its possible I guess... as suggested though- stop it and see. How much have you been giving? Its really good for reflux too btw. And nutritious- not just a yummy looking mucilaginous goopy paste

It soothes the digestive tract, well all the soft tissues really, and helps maintain a nice mucousy membrane. Its a very ancient remedy- used for centuries... with babies too.
Did it help the constipation?
We had lots of these issues w Locks too... its so hard when things keep piling up... and sometimes (not always) they are unrelated.
Excema is a reaction... however- it could be to so many things... food, environment, chemicals, even hormones!
I agree your doc sounds a bit 'head in the sand'.
Babies with reflux can definitely have probs feeding- sometimes as its really uncomfortable... to be horizontal etc... the milk just comes up, burns etc
Once their little throats are burned from the acid, its a bit of a spiral.... hard to soothe a throat that keeps getting burnt.
Another reason why slipery elm is good too though.
Thinking back- L's excema started off with the hormone spots type thing- then went into full scale excema all over his face the poor monkey. Its hard when theyre so young and you feel youre trying everything.... we used exmaease about 6 times a day, and then went onto Tui balm once it had cleared a fair bit... (exma ease is all natural- great but $$)
There are other natural things to try for reflux too... if you feel this might be the cause of the feeding prob.
We started L on solids at 4 months- I think he was born to eat food, not drink milk... I could never keep up with demand, and he was miles happier, healthier on food.... I wouldnt have done it much earlier though personally. Everyone is different
