Hi My baby has very dry lips and ulser. She is not able to open her mouth. Please suggest some medicine.

A. hi ji ,dry lips aur ulcer pani k kum intake se jyada hote he wese to ulcers ,constipation ya fir nutritional deficiencies k karan hote he to pehle to bachche ko achche se hydrate rakhe aur uske diet me prebiotics food items jese ki banana , tomatoes ,oats , flax seeds aadi de ,jo constipation ki problem to dur krengi but sath me ye jo flolic ya fir koi aur deficiency rehti he wo bhi thik krne me help krta he.
