My ds is 13 weeks and is starting to teeth (sp?). He is constantly sucking and biting his fists and has made them quite sore. Have tryed teething rings etc but are a bit small for his mouth as is only teeny and he prefers his hand. Have tried putting scratch mitts on him but he screams blue murder when i do, any suggestions? is there any cream i can put on them that is ok to use if he is putting in mouth as they look really sore?
