Help! Baby hates food

I’m a first-time mom, I need some advice! My eight-month-old is happy and healthy and right on track for his weight, and he drinks milk like a champion, but he HATES food. He hates baby food, he hates the rice cereal, we have tried him on Puffs, he hates those too. This is his his face when he eats. 🤢 Should I take this as a sign that he’s just not ready, and try again in a month or so? Or should I keep pushing it? Or is this something I should call the doctor about?
