Get him some teething tablets from Wal-Mart or Kroger. They are Highlands Teething Tablets and they are awesome! Matthew began drooling at 3 months, so I knew we were in for some tough times with the teeth. Someone else told me about them and they became my magic pills! I would start out with about 3 to 5 and then you can give them up to 4 to 6 times a day. They are completely safe (called Poison Control) and they just take the edge off some they can rest and REST is what I needed!!
I highly recommend them and have had friends come by my house to get some when their kids were going through the same thing!! The oragel and other things were terrible, the teething tablets melt instantly when they are on the tongue, so no harm!
Great tablets and I had them all over the house, diaper bag, pac & play, my purse so I wouldn't have to search for them when I needed them!!
