A:AnswerIt may be possible for the device to track steps when worn on an ankle since the vivofit 2 uses built-in accelerometers to track movement, but the device is designed to be worn on the wrist and is the recommended method for wearing the device. -JFH
A:AnswerThe vivofit 2 comes with two bands. The smaller of the two has numerous oval latches that could be adjusted to fit a small wrist. Depending on size it still would have about a five to six inch face where the information. I.e. Steps, time shows. This part may be too big on top of wrist.
A:AnswerI have had mine for a year and a half with near daily wearing and have not experienced any wrist pain whatsoever. I keep my band just loose enough so that it can slide a little on my wrist but not enough to rotate around my wrist.
A:AnswerThe device is to be worn all of the time so wear it in the shower and can't say that it performs any worse because of that. The size of the child's wrist would be the determining factor on fit. It does need to be snug.
A:AnswerThe vívofit 2 uses two CR1632 coin cells, which should allow the vívofit 2 to get up to over a year of battery life. If seeing less than this, please contact Garmin Customer Care for assistance and troubleshooting: http://garmin.com/support

A:AnswerThe vívofit 2 syncs via a small ANT plugin device (included in the box) inserted into a USB port on the computer. As long as the Windows 7 computer has a port, you should be fine. \tw/
A:AnswerThe band goes quite small so it should fit a smaller wrist. My measurements say it should fit a wrist down to about 2 inches across at the lowest. The instrument package is limit to the size so at that size it might be uncomfortable to wear.
