All kids are different. Most people's experiences won't be the same as yours. Psychologists actually do a decent job at comparing experiences, but they don't really give useful advice, only help you to understand that it's normal.

Whatever it is, you probably have to wing it. Be mindful and observe everything.

Everything is a system. Kids act on each other and on you. It's sometimes a balancing loop, sometimes a reinforcing loop, aka they'll fight or they'll keep each other in check. Systems engineering helps a ton in discipline. People say parenting is the hardest job but IMO it doesn't have to be. The nature of systems is that they're stable without any outside action. If you're kids aren't brushing their teeth or wearing their seatbelts, check your system.

But one major piece of advice: (My) Kids can't sleep when they're too tired, and they end up tired all the time because they don't sleep. Again, this doesn't apply to all parents - one of my friends has kids who would run and climb everything until they're red in the face, and they'd behave if given that outlet. But try to get them to sleep early, especially as babies.
