Find what he likes and build off of that. Is he picky or just doesn’t like food mixed? For instance. A toddler might not like an enchilada, but likes a tortilla and cheese separate. My toddler isn’t very picky, but likes lots of whole foods . She’s often snacking on a whole carrot or an apple, or a chunk of cheddar cheese. Eggs are good for protein- there are so many ways to make them, you might find a texture he likes. I used to have to make my daughter’s eggs a specific way- I’m not even sure if it has a name, but flat, in one piece and sliced, but with the yolk broken and cooked into it. Also some things she eats best if fed. She likes soup, but it’s hard for her to eat it unless I feed it to her- then she will eat a whole bowl! She also went through phases. She went through a time she basically only ate eggs and strawberries and then another time where all she would eat was green beans 😂. I went with it, but tried to offer something enticing, something off of Mommy’s plate always seemed more appealing to her.
