This cute wristband, called a milkbands, gives you an easy way to keep track of whick breast the your child fed from last by just turning it inside out. One side of the band/bracelet says "left" and the other "right". It also has little markers to indicate how long the feeding was. I am not sure how useful these are and they do seem like a choking/swallowing hazard, which the manufacturers mention as well. The bans look very similar to the ones that people wear to support a cause or interest, so you can wear it out and not feel strange about it.
