I think Motrin can make a babe hyper, Tylonal might be better if you want to try it. My little dude never chews anything but if he opens his mouth you can so see the irritation and it lasts for MONTHS! I never know what it is.
Well, hoping for some advise then. Something has to be going on at this age -- sort of like 12 months but a year later and double frustrating (triple for you since your LO is due soon, congrats by the way!!)
