This is the ONE thing I recommend to all expecting mamas!! I LOVE this necklace. We had one for our daughter and it was amazing. We lost it for what weeks and it was a nightmare!! She was a drool monster and wouldn't sleep thru the night. I went and bought a new one and it was a complete change!!! I'd say just for the drooling part of teething this necklace is amazing!! Cuts drool down by at least 85%!!Only reason this isn't a 5, is bc the bracket was very small. I have a new baby who isn't super chunky, and he has small wrists, but it wont fit.. so we use the necklace only.But I STILL LOVE THIS NECKLACE!!
