This. As a father of three kids it's sometimes fun to look at people going through this – you are the smartest person about kids if you don't own any yet and most stupid one with the second one if you realize that you can't reuse almost any knowledge you gained with your firstborn. By the time you have a third one, you've already accepted that they are all very different and you have to learn from them, grow with them and adapt.
