I have a teething bracelet on DS because I am just paranoid about the necklace being around his neck. He has only had it on for a week and it might just be coincidence, but he doesn't "bite" me during feedings when he has it on. We lost it for a day and he was back to biting my nips. He also doesn't slobber as much. Again, could just be coincidence.
Re: Teething Necklaces
OMG, remove it.
And do they work for you?
Just ordered one on the internet, didn't receive yet!
Definitely remove it.
We also remove bibs etc once our LO is sleep.
