What can I do with my fully bf 10 mths old baby? He has ulcer at the tip of his tongue. Cry whenever his mouth are dry during sleeping as it is super painful. Apparently bonjela doesn't work.

Ouch. Tip of the tongue is very painful even for adults. Bonjela works for awhile only. I would recommend hand express some milk to gently dap on his lips to moisture the lips and the extra milk will seep into his lips and moisturize the usclers.
