Well Boo has most of his teeth now. We bought him a teething necklace early on in life and he's worn it ever since. Now granted, it's hard to know if it worked because he's worn it pretty much ever since he started teething. But I will say, other than a few restless nights here and there I can't really remember a time when he was horribly miserable from teething. So I feel like this teething necklace actually works. I wasn't sure what I thought when I bought it, but I figured if it didn't work he'd at least have a stylish necklace!
Anyways, here's a link to the site where I bought mine. There's lots of places online to order them. This place was cheaper than some others and I'm happy with the quality of his necklace.
