Aptamil Pepti was the only one ours would drink. Hydrolysed but less awful tasting than amino acid ones.

Neocate is amino acid - last resort for severe cases. Hard to get on prescription unless others fail.

Start while baby still BF (introduce mixed) - easier acceptance than going formula-only cold.

Nutramigen smelled and tasted truly terrible. Even the dog refused it. We switched.

Warm it more than normal milk. Helps mask the taste.
