When did you first feel like a real dad?

My son is 2 months old now and I'm still having moments where I'm like wait, this is my kid, this is real. But last night my wife was exhausted so I just took him, got him calmed down, fed him, changed him, got him to sleep. Did the whole thing myself without panicking and it felt different, like I actually knew what I was doing. That was the moment it hit me that I'm not just helping out anymore, I'm actually a dad. Anyone else have a moment like that where it clicked?
