Took paternity leave and didn't regret a single day
Just came back from 8 weeks off after my second son was born. I know not every guy gets that option but if your company offers it, take it. I learned how to change diapers, how to soothe a crying baby, and I actually got to bond with my newborn instead of my wife being the only one who knows all his routines. The work was still there when I got back. My kids won't be this small forever. That's all I'm saying.
Eight weeks is the dream. I got two weeks and it still changed everything about how I look at being a dad. Even that short window does something to you.
