I too through this at a time, but four kids later Having four they can keep them selves busy. Plus as they get older and start to drive we have more choices of drivers to cart others who can't yet.
We even have two dogs and two cats so they aren't left out either.
The final card for only one kid was the health problems that my son had. We were warned the next kid may not be so lucky.. Soo It's one boy only.. I couldn't be happier then i am with Grant. Four kids John.. your either brave, crazy or some word i can't say here.. Sounds like you have it together.
