Hello, my 2 yo has HFM. He's not able to get down anything but water. He begs for food and then cries hysterically because it hurts his lips and mouth. He's on nurofen and alternatively calpol. We've tried yogurt, soft mashed potato, blended porridge, mashed banana, milk with straw/in cup/ in syringe and no luck. GP wasn't very helpful. Are there any gels I could use on his mouth? Any other ideas?
