just like with a puppy.. consistency... kids being young are not aware of their strength.. and grasping a moving tail is fun..well.. not for the kitty..lol.. but if they are putting with it AND still staying within reach.. it probably means they are not that bothered.. but supervision is always a must

with kids everything happens within the blink of an eye.. so just keep all four attentive for those funny furry feeling baby grasps...
