I can't imagine any scenario where it would be taken "kindly" for a brother to tell a sister to do something about a snoring infant.
"To tell a sister?" Well, in this case he told a brother. Does that make some sort of difference?
Obviously we disagree about this. And this was just how things used to work in the congregation. Whether it had to do with distractions or the temperature, lots of disagreements. Some are too hot, some are too cold. Those too hot suggest the cold ones should bring a sweater. Those too cold recommend the hot ones taking their jackets off.
I'm glad that snoring doesn't bother you. It usually doesn't me either--unless it gets loud. Then it's not an issue of it being a child. It's a loud noise, and I can guarantee you that plenty of people are irritated by loud noises when they're trying to listen to something. And these people come marching up to the nearest elder to complain. You may believe them to be "crotchety." They may have opinions of you too.
I thank God I have no part of these meetings anymore, but I can tell you that, in my experience, elders were usually doing their level best to make sure people were kept as happy as possible and that their complaints were considered. You can bet plenty were not satisfied--no matter what was done--or not done.
