I'm onto my third 2yo, and they've all been different.
Dd1 went from a tiny girl who ate everything to a really fussy 2yo and has gone on to eat vast quantities of lots of things.
Dd2 eats everything. She always has (she's currently 2).
DS however only ate about 5 things until about 12 months ago. He's 5. At that age it was only white food except potato. White bread, rice crackers, apple without the skin...very few things....very very frustrating.
Now at 5 he's finally trying new things. We've added strawberries, watermelon, bananas, meat and quite a few veggies, cheese even. He's always been a sensory kiddo and I think texture is a big deal for him. When you add in the senses of taste and smell, sometimes he got overwhelmed. Letting him choose and play with food at his own pace has helped.
Fwiw he was introduced to food the same way as his sisters, same approach, just a totally different kid.
