@syncakes Will only eat 5 types of food? Been there.
Only loves beige food? Wore the t-shirt.
But I wouldn't turn down the advice to keep trying to offer a variety. It takes about 50 tries before a child will eat some food. What worked well for us was serving 1 food they loved in small quantities, along with one food they knew but sorta hated, and one brand new food. We required a try for all 3 before a second serving could be obtained.
A try could be: touched the food, licked the food, put food in mouth and then spit it out, or ingested it. And yes, it sounds wasteful. But I just had to resign myself that I'd have to throw out food. Toddlers, man.
I'm not gonna say it worked overnight (see: 50 tries), but eventually my super picky eater became an adventurous eater, and my good eater got pickier, but in the sense that he grumbles a lot, but will still touch most plates. It's a marathon, not a sprint, and your kid will get there.
And for those who feel desperate, I like to tell the story of my friend Nick (*not actual name). He was a terrible picky eater into adulthood. We're talking "won't eat a burger if there's anything but ketchup on it, and don't you dare to offer it on anything other than a white bread bun". Like, we'd invite him to Cracker Barrel or other inoffensive places, and he'd end up not eating on a technicality.
Then he moved halfway across the country and made friends who loved to go out to eat and try different cuisines. He figured out he needed to get over his issues, or he'd burn a lot of bridges. And he did. In his 30s.
So there's hope there.
