Big congrats to you both. We have a 12, 10 and 9 month old. Last one was our mid life crisis.
I couldn't imagine I had room in my heart for another kid but as soon as you see them they become part of you forever. It's hard work to be sure but you won't regret a second of it.
Those without kids may be financially better off but they are infinitely poorer in the end.
Good luck bud
