I too was part of raising children and feeling neglectful of the whole family since I was gone so much while staying employed for us.
For me though children are for the young but having a younger wife would help in that department but my wife of 40 years is just fine.
My wife is 25 years my junior, I am actually older than her mom.
To make it worse there is a wife's sister, sister's daughter (13), maid, and another woman worker to look after my spoiled daughter.
So I pass off the daughter to one of 5 other females when I am overwhelmed. I kind of forget that part, so yes, if it were just my wife and self, egad!!!!
