so the dcb who always wears one, apparently is vomiting at night (mom says its his sinuss draining so its making him do it, but I have a feeling its way too much milk, because he doesn't do this at nap time) well all day he smelled like vomit, she said that she washed him up. Well, there is no way, that stupid necklace smelled like vomit so bad, so I took it off. His hair smelled like it too. But anyways, I noticed that it was leaving a weird marking around his neck from wearing it. This kid has never taken it off, but I will say, I was shocked at how much gunk was on this necklace, totally breading bacteria.
