Happy birthday to your daughter, being a father twice is not an easy phase in life, I think you just passed the gender stage to number, I know for sure the europeans are okay with a smaller numbers, my dad's boss a European lady will always say to him "John! 3 would have been okay since you go with 4, it's okay".
You were right when you said raising a girl requires much, not just the money, in adolescent the time, attention, observation is another thing we must sacrifice..
Greet your wife for me, she has a rationale behind her choice, happy celebration, I wish you a happy married life, Goodluck sir
