Congratulations to you and your wife. Just a thought to ponder. I had twins first and when they were born, I wished they were a month old so they could smile at me. When they were a month old, I wished they were 3 months old so they could respond to me more, when they were 3 months old, I wished they were 9 months old so they could walk, when they were 9 months old, I wished they were 3 years old so they could..., ..., ...,
When they were 3 years old, I wished they were newborns again.
Enjoy every minute, no matter how good or bad it seems at the time. You will miss it someday.
