Y'all my little 3 monther is teething! He's drooling like crazy, running a low grade fever, really fussy, his gums are super swollen. For about a week now. So I've been giving him Tylenol, Teething tabs, Oragel (most say don't but it didn't hurt my first two so), got him teething toys that I put in the freezer. And hes still super fussy!,

Is there anything else y'all know that helps??
