Around half way through I started to ask myself if this sort of thing is child abuse.
No, it is not child abuse. No one was forcing the kids to taste the lemon, there was no pain and no injury. Infants have highly sensitive sense of taste and I've seen them make the same kinds of faces when they eat common foods like green beans. Is it child abuse to feed these kids green beans?
Obviously spoken by some one who doesn't have children!
