If you want your daughter to enjoy riding a bike, buy the 16"; as she grows, raise the saddle and tilt the handlebars forward to accommodate. From now until she gets her driver's license, buy the next size only when she's truly too big for her present bike. This means that you'll buy at most only one extra bike. And probably not even that: she'll be able to go from the 16" to the 20" (if you adjust the 16" bike as she grows, she won't need an 18" bike), and many kids are happy to stick with 20" bikes (witness the 6'2" kids riding 20" bikes around your neighborhood).
