Sienna is 3 months old today. For the past week or so she has been gumming everything! She shifts her binky to the side and chews on it, same with bottle nipples, anything near her mouth gets chewed on. She also has been drooling constantly & super fussy...do you think she can possibly be teething this early? If so...what can I do for her? She is still too little to hold a teething ring in her own mouth - I've tried! But I am working from home now and can't constantly be holding a ring in her mouth...what to do?
