I wish I could help you more…Jonah was an early teether- got his first tooth at 4 months also…but he was smack dab in the middle of reflux HELL at the time, so poor baby just shrieked and howled no matter what- tooth pain, reflux pain…so I can’t tell you what worked at that point- as he was older then the usual things- hylands, tylenol, motrin, benedryl…
Ari got his first tooth later than Jonah did and benedryl on the gums, tylenol and some hylands have been all he needs (KNOCK ON WOOD!!)…
