I've got one. My mum gave me one when I was about 12. I have a key, heart-ancker-cross, shoe, dove, bike, angel, scissors, doll, car. Now that I look at it it is not alot. Hmmmm..... will go and get some more over the weekend!
I bought my DD (11months) a charm bracelet for christmas with her first charm - a dummy - and I'm going to give her a charm every christmas eve.
