It's a strange thing feeding another human being. Even stranger when a fussy eater is feeding their non-fussy eater child. I spend long periods of time faking smiles and satisfied noises about food I wouldn't dream of eating myself.
It's these people, and their blissful ignorance, that contemporary parents must learn to navigate around. Like hidden rocks among the flotsam and jetsam of parenting - they must be spotted and avoided if possible.
