Rather than the usual devices that need to be attached to the wall, or the door way, this is basically a folding measuring rod with cute little illustrations and a place to put the name and the date of birth and you can measure and record whenever you want to. And when you are moving, well, then you just take it along and don’t worry about finding another spot for the permanent one…  Cute, practical, perfect for kids to play around with!  Available at Charles and Marie.
