Congrats. It’s always a little daunting coming home for the first time. The sleep depravation takes some getting used to. I have identical twins (and my brother has identical twins and my other brother and his wife were pregnant with twin boys and miscarried), so I don’t remember a lot of the first year, other than to say I survived it. Take the time to enjoy each age. Make time to spend time with your kid and your wife. Run a little less, spend more time changing diapers, reading books with your children (you will not regret it later) and going to your kids soccer practice.
