How long does teething symptoms last like chewing his fist, fingers, loss of apetite, fussy, wants to be held all time so than he can press his jaws on our shoulders. I feel very sad seeing him like this.

A. it might take a while to go. you can help by massaging the gums with a moist clean cotton cloth 4 to 5 times in a day and gibe cold silicone teethers to chew on them. start brushing using a silicome finger brush
