13 month old and eating.

It’s been about week 2 since my son isn’t eating very much, I’m trying everything I can. He was teething nonstop the past weeks and has so many teeth and now he just doesn’t really want to eat ANYTHING I give him. He’ll have some bites here and there and usually for breakfast he’ll eat most of his food, but overall he’s just throwing his food. I’m thinking he’s bored of the foods I make him so I’ve been trying different things, but he still will just throw most of his food. It’s been really frustrating recently because I just want him to eat and be healthy. Haven’t spoken to his doctor...yet. Poop, pee and weight is normal. He hasn’t been really cranky or having any other issues. I’m just so tired of making so many meals and he just doesn’t want to eat.
