I have been told by a doctor that my 2month old baby has extrapyramidal symptoms (EPS), but after reading about what this is, I cannot believe that she has this. He looked at her and told me that the fact that she is lifting her head up quite high for her age, that she has these symptoms. She used a colic mixture which contains Diphenhydramine and he told us to stop with this mixture. However, after reading about EPS, everyone suggests Diphenhydramine as a treatment for EPS. Please help. How does a doctor establish whether a 2 month old baby has EPS?
