Spot on MrTPlush!!!
Excellent idea to start a thread on little league coaching. I've been coaching my two oldest kids the last several years and took the jump to head coaching last year, which included All Stars for the oldest. I was hesitant because I thought I needed to wait until they got older but it was a lot of fun! If you have any specific questions, go ahead and shoot, I'd be glad to help the best I can. This will be a good place to come back to as the season gets going.
As for videos to watch, I'd maybe start with the little league YouTube channel. They have a lot of basic how to videos on there. I've also found some good content from this page, but he has a lot of videos. There is so much online content and beliefs on how to do things that it can get confusing.

The biggest thing is there are going to be so many different skill levels in little league. Some kids at the kid pitch level will still not be able to catch a ball well, while others are starting to figure things out and need more detailed instruction. Last year was my oldest's first year of kid pitch. My middle son is going from rookie ball, which is machine pitch (they use a tee if they miss the first 3 times and everyone hits every inning, no rules or scoring because everyone scores every inning), to A ball which is machine pitch but they are playing baseball rules.
Best of luck with coaching this year!
