I recently had an experience where 13 month old dcg removed her amber necklace at nap time and when I went in it was slimy and partly in her mouth. That day the mother got a note that jewelry is a liability in my dc and not allowed anymore. I have 5 to get ready for nap and shouldn't be responsible for one more thing. If that child had choked it was my dc on the line. Mom agreed thank goodness
