My 9.5 months old baby boy has suddenly stopped eating solids. It seems that he is not able to swallow it. He keeps foods in his mouth and will swallow only when he is given water else he will gag or put his finger in his mouth to induce vomiting. I had tried watery consistency to thicker consistency but nothing helps. What could be the reason and how do I get him back to eating again. His teething started when he was 8 months old so I doubt teething could be an issue.
