Parents who have never had problems with DC and food can come over all smug when telling others how it's done. You know - don't give them 'junk',don't offer alternatives, don't make a fuss, ' my 10 month old loves foie gras and quails' eggs' sort of thing. I know because I was that parent ( not foie gras though!). At least with DS1- and me being a Food Tech teacher and all. I knew it all and DS1 had a voracious appetite - still has- and gobbled everything up.
DS2 then pulled me up short. 2 months premature but soon piled on the weight,took to solid food fine and then at the age of about 18 months got increasingly fussy to the point of excluding fruit, veg, anything not instantly identifiable so no sauces etc. and generally favouring junk.
It wasn't ' just a phase' as it turned out but I spent years with no help, lots of ' tut tuts' and a feeling of failure. My knowledge of nutrition helped me ensure he got a healthy ( if restricted) intake of essential nutrients and I developed a thick skin.
It's a long story but turned out he had / has sensory issues related to atypical Aspergers. Ironically, his brother has full-blown AS and eats like a horse.
The throwaway line about no 'normal' child starving itself has a hollow ring for me as I considered my son ' normal' and, actually, I still do.But children with sensory issues often don't appear any different to others in most other ways but they will starve themselves if not handled flexibly.
