I know it's gunna sound crazy but, is it possible for my son to be starting teething at 2 months?? He has been uncharacteristically irritable the past few days, crying nonstop and having trouble sleeping. He sucks hard on and bites on anything you put in his mouth. He is drooling bad. And today I noticed a little white spot coming out of his gums (this is obviously the point that makes me think teething). All the books and websites say not until 3 months but is it possible for him to get his earlier?
