I hear ya.
I’m 47 with a 2 year old, soon to be 3 and a 6 year old….. and the wife wants more.
I tell people that I wish I had started a family 20 years sooner but I think I’m a better dad now than I would have been in my mid 20’s. Now I’m more laid back and a little smarter.
Officially 56 years old. For the last 10 years or so, my wife needs to remind me of my age. I always think I'm one year younger then I actually am - go figure. I normally don't have trouble with simple math but the age thing seems to be the exception.
