Also got ours from Amberbebe - LOVE it! I can totally notice a difference when he hasn't worn it the day before... Our little man is also an early teether, one has cut through already and 2 more are on their way - We didn't even know he was teething until we saw that first tooth! He didn't make a peep until it was almost all the way out! I contribute this entirely to his Amber necklace which he has been wearing since 12 weeks old - $50 well spent in my opinion! Good luck!! xx
