My baby boy has been teething for 2.5 months now and he still has not cut a single tooth. He is only 5 months old and I know that the first tooth may not come in until at least 6 months, but it's to the point where it's messing up his sleep (he's up every 1-2 hours crying and trying to bite his hands or my chin) I read a bunch of articles that say he should really only be bothered when his gums are about to erupt (up to 8 days) but it has been months!! He is drooling excessively, wants to constantly bite something but won't take a teether and is extremely irritable. I feel like this is an excessive amount of time for him to be this uncomfortable and irritated. Has anyone else experienced anything similar to this?
