Yep, mine too. DD1, 10 months old, was happy with a well-chopped piece of my Frfiday fillet steak, buttered jacket potato, peas. Or any suitably mashed version of what we were having. One day, no idea when, zipped lip and cried at the same foods she used to love.
DD2 - I used to make a lovely spaghetti bolognese with mince and home-made sauce. Used to laugh with delight when she saw it coming. One day... yes, sat in front of it and zipped up, thrust bowl off table and refused it absolutely from then on.
I don't think I'm a 'shit parent' as someone smugly decreed from their lofty tower of smug; DDs are in their 30s and 40s now and eat a variety of foods, one is mostly plant-based, the other loves meat but still won't have it in sauce, both healthy adults with their own preferences, different from one another despite the same upbringing.
Absolutely agree with those who say there's an MN 'thing' where everything British is shit. You don't need to google far to see it's absolutely untrue that other countries never give their young children a 'child-friendly menu.' And yet the MN Smuggers maintain in countless threads that never happens, and that if I'd only not been such a shit parent, mine too would have eaten everything put before them.
Another MN 'thing' is, 'I do everything right and my friend's child could be like mine if she were more like ME and not so lazy/ignorant/uncaring.' Gah. I think I've finally outgrown MN, it's just so irritating and predictable.
