Although I've used regular infant scales in the past, including the standard $14 "home nursery" spring scale (it gives relative weight and is true to itself), I prefer the hand-held hanging scale (the Salter spring scale) that can travel easily and has a hammock-type sling that hangs from it for baby to lie in while being weighed . These are readily available for retail merchants, but your best bet is through sporting goods stores - ask for a "fish and game hanging scale". They come in all sizes to weigh from small amounts (up to 6 pounds or 2 tons!!). A quick 'Net search using (including the quoatation marks) "weighing scales" and "hanging scales" yielded lots of links. Here's a few - (you'll probably have to make your own sling to suspend from the scale): An American scale company: http://www.chatillon.com/products/scales/ A tutorial (a very good one, too!!) on human anthropometry with information on scales including one from UNICEF: http://www.odc.com/anthro/tutorial/tunit14.html UNICEF hanging scale - (UNICEF catalogue no. 01 455 50) This is a Salter type spring scale with a capacity of 25 kg and 100 g gradations.
