If you are “EmotionallyUnstable” now, wait till your wife’s postpartum depression sets in.
Just kidding - it’s the most beautiful and scary thing I’ve ever experienced. I now have 6 grandkids and this is far easier than bringing up 3 daughters.
You’ll learn things about yourself and accomplish things you never imagined. Make it your focus in life to be a good husband first and foremost, and then a great Dad. Your partnership with your wife needs to be strong to make you the best Dad you can be. I failed at that, so I’m speaking from experience. Your children benefit the most from a strong marriage.
