wah lau... simi tai chi......!!!!
Never had that problem with my boys. 
Yup, cane the kids or hang them out to dry or slap them till they
turn blue.
Most churches nowadays are equipped with a cry-room. However most
of the time, such cry rooms are turned into gossip centers.
At the end of the day the problem lies with the adults, they are
either:
Not willing to discipline the children, allowing
them to cry, yell, throw tantrum as and when they like,
Basically boh-chap as they are worshipping and
allow the kids to do whatever they like,
Or inconsiderate that they do not clean up after
themselves. No auto-gear.
Some even condone their own kids running in the
sanctuary during service.
Like I said, I never had this problem. Even during toddler stage,
they are not allowed to throw tantrum. Both my sons, even now, do
not throw tantrum.
Sigh!!! 
The joy of being able to use the cane......
whey they were younger.
