We've been eating once a day for four days now, 120 ml ?. I'm emotionally devastated. I don't even know what to give anymore. Today, the yogurt was barely eaten. She ate 20ml of mashed pear and 4 tablespoons of yogurt, and that's it. But the mixture, not even porridge wants to eat. She doesn't want to eat anything. The teeth are poking out ?‍♂️. There is no fever. Yesterday she ate rice porridge at night, but today she had diarrhea. How did your kids eat when they were teething and how does this end?
