Personally i don't have children so i'm unable to speak from first hand experience but there are lots of owners on here who have bengals and young children. In fact quite a lot of people say young children are brilliant with bengals because they keep each other entertained as they both have so much energy
I think especially if you could get a bengal from a breeder who has young children who interact with the kittens, that would only make the transition even easier. Just make sure they are well socialized because then they will settle in easier.
My bengal is the most gentle, good tempered cat i have ever come across, you can literally carry him around like a baby. If someone were to bring kids to my house, i know i would definitely trust him around them if that's any help!
