Anti-itch for Infants

[jtar]

Is there anything safe for infants that can help sooth skin and prevent itching?
--------------------
Our son is nearly four months old, but for the last month has been suffering through a terrible and itchy rash.

Our doctor first thought it was a topical reaction, but his diaper tested positive for blood, so they called it a food-related allergy.

My wife has been eating nothing but meat, vegitables and salads in order to rule out everything, but he is still rashy and now that he has better hand control will scratch open his cheeks and face.

We have tried the standard pink baby cream, Cetiphil, Eucerin, vasoline, even shae butter and olive oil.  We cut baths back to much less frequently.  We are keeping the house at a good temperature and adding moisture back into the air.

My wife has not had dairy for three weeks and has been off 'everything else' for almost two weeks, but our son is still thrashy and rashy.

His cheeks weep during the night and will be wet to the touch by morning.  His elbows and lower legs are still the most bumpy and he has trouble holding still and not scratching even to eat.

Any advice would be appreciated.
