That depends on how much they've been socialized, and how children treat them.
My male shiba was introduced to my three nieces (ages 3, 9 and 10), and my neighbors' sons (ages 4, 7 and 13) when he was 8 weeks old. They were gentle with him and gave him a little treat and he's loved children ever since. Every time we pass families on our walks he gets so excited to say hello and get petted that his whole body wiggles.
He can play a little rough though, and a hyper, playful child is going to bring out the same in him.
And if the child doesn't respect my shiba's boundaries when he backs off, or they try to pick him up, or tug his tail, etc. he won't put up with it for very long before he growls and snaps.
