Hi, Amanda –
You may want to check with your pediatrician about the Hyland’s teething tablets before using them. Although many pediatricians do recommend them, mine warned strongly against them because of their tiny amounts of a few ingredients. (Don’t quote me, but I want to say it was a trace amount of opium or something). That said, I do know that a lot of parents have used them, and swear by them. I've heard that they do work well.
One suggestion we received (and were extremely grateful for!) was using a frozen waffle. This may not work for your son because he doesn’t seem to go for the cold stuff, but you may want to give it a try. It’s just soft enough that babies can gnaw on it a bit, but hard enough that it takes some time, and provides some relief. (And, we used some pretty darn healthy ones, too, so he did get a nutritious snack in the process). :)
Teething isn’t fun. We’re still waiting on some late-appearance 2yr molars, and I’m not looking forward to it. Hang in there!
