my suggestion is whites tree frogs. they look like kermit. Not real active in the day, although they will wait in appointed feeding spot. They are friendly enough to eat from your fingers. Same as you, my son wanted frogs. Through my study, pacman frogs bite, cubans are toxic enough to cause alergies. And fire bellys toxic. Whites are the most handleable frogs. Simply washing hands after handling. I've had mine 3 weeks and they know when it's feeding time and will stay awake to be fed. They are 2 1/2 and 3 inches in a 33 gal tank. My 3 year old hasn't held them yet (suprise) since we are waiting for them to adjust to new noisey environment. Good luck with your choice. But the kids will want sumthing to hold eventually. I suggest getting cage going and ready before u bring frogs home.
