DON'T DO IT.
Whoops, let me rephrase that. Please follow your doctor's advice, and if s/he says do it, then do it unless/until you agree on a possible alternative. On the other hand if you're perfectly happy doing lid scrubs and your eyes are doing great, that's great and you should ignore this page altogether.
We are relieved to hear that amongst eye doctors, baby shampoo is finally starting to fall into disfavor as a blepharitis treatment because it is simply too harsh for chronically dry, sensitive eyes. Also, unfortunately directions with respect to dilution seem to be all over the map and we hear now and then from patients who are applying undiluted shampoo to their eyelids. Not good.
