I think the most striking for me with my first is that I felt a lot of things were suddenly out of my control, while there's always things to worry about, I never really worried that much, but the significance of having to look after another human life suddenly hit me and I realized there are a lot of things that can go wrong that, even if you take precautions, there's no guarantees. Which is generally true, but when it's about someones life other than your own, it feels a whole lot more significant. However, after that, as a Dad, for the first 6-9months, you are pretty insignificant other than as a helper, but as your kids become more interactive, being a dad starts becoming fun. Then there is a super sweet spot from 4->14 (ish, different with different kids) that you have to take EVERY opportunity to enjoy and engage with as much as possible. All during this time I also was improving myself as a developer also.
