Not sure if I've posted in the right section but anyhow...
I just noticed today that my 4 1/2 month old DS's poo smelt strongly of vinegar and was very acidic in texture. It wasnt green, but a yellow mustardy colour. He's never had this before. He also has no issues of reflux etc. He is ebf.
I can't really find any info online - only the fact that he may be getting too much foremilk. Does anyone know what else may be causing this?
