It comes down to exposure and training. As long as the chi is exposed to kids, well trained, and the kids know how to act around a chi, they get along well.
Toby adores children! The first time he met my goddaughter, I was reasonably nervous. He's always been good with kids, but he's never really been around them more than in passing, saying hello, etc. We went to lunch with my best friend and my goddaughter desperately wanted to hold him in her high chair. She was around 16 months old at the time. I sat really close to her with him in my lap. She was nicely petting him when all the sudden he stood up and gave her a big sloppy kiss. She giggled. Then they were best friends. He sat with her in her stroller and followed her while she crawled around. He adored her! I was proud.
Since then, he's been around her and several young children and been great. He still adores his Amelia, my goddaughter. She'll be two in December and when they last saw each other in August they were running to each other (well he was running, she was just learning to walk) like star crossed lovers.
I think that as long as the kids know boundaries and aren't torturing the dog and the dog is taught how to act, it will be fine. As with any dog, though, never leave the chi alone with the child.
