Hello, moms. My son has always had a good appetite, but it has decreased over the past month. He might eat only once or at most twice a day, sometimes just snacking on apples, kefir, or meat. He's not teething right now, nothing hurts, and he's lively and active. His portion size has decreased, and he has stopped eating soups altogether, which has really shocked me. He will be two years old in March. Can anyone advise what to do? Am I just overreacting?
