Has anyone used any for their kids while in the parks? I'm not looking into anything elaborate (i.e. not dropping the $ on Brickhouse), but I was considering one of the Mommy I'm Here bears...probably the blue ones w/ the alert feature (vs the pink or brown model). We're already going to be using Safety Tats + take pics of the kids w/each outfit change and use easier to pick out hair decorations (we usually go for big flowers)...but looking for that extra peace of mind. Considering DD4's propensity to lag behind in the supermarket- it probably would come in handy for more than just a trip to Disney.
