I’d read some Ellen Satter on the subject. At the rate you’re going, you’ll either be a short order cook or eat breakfast for dinner as a family through her childhood. Neither is a good idea.
Around that age I started doing a modified Ellen Satter approach. I’d have something on the table my child would like and and offer reasonably kid-friendly foods. For foods he didn’t like (usually a vegetable), I told him it was his choice, but if he wanted dessert, he had to have a couple of bites. I didn’t force him, so it was his decision. Most of the time he wanted a cookie more than he feared the carrots

. And I was flexible. He was willing to eat the stem of the broccoli, not the floret, so that’s all he had to eat. It worked for us.
