Huge fan of the Leupold 6X for kiddos. Like them so much, I usually use them myself when deer hunting in IN.
Only fault I've found with my sample of one is the eye cups not staying extended.
For young folks who might want to look at nature as well as look for deer, Pentax makes a smaller binocular that can focus from 20 inches to wherever. It's called Papillio.
With our Master Naturalists, we use them in to look at insects like butterflies and dragonflies as well as birds where we don't need 10X or more. They are resonalbly small, light and decent glass and are nice especially with kids or adults like me who get bored looking way off somewhere. They are available in 6.5 and 8.5 powers and are usually $100-125. They are not Swaros and are not for hard core Alaskan guides, but nice, smaller clear, lightweights. I have the 6.5's, but I find that for distance detail birding and deer hunting, like my old 7x35's thay are a little weak. BUt I have old eyes and prefer my old, heavy10X Kahles for that.

As wonderful as they may be, I'd be leery of buying Pentax optics if support down the road is of any concern.
When Pentax was sold to Ricoh they reduced the Sport Optics customer service dept to 1 person. They basically turned sport optics into the unwanted step child. We, at that time, stopped carrying their products. We cannot sell product that we cannot offer quality customer service on.
