+1, Sarah.
I carried my middle child around until he was about 7. He was unusually small and I enjoyed carrying him. At the time, I thought he was my last child, so maybe it was more for me than for him! 
One little slice of time doesn't tell us much about how parents are doing with their children. Heaven knows I'd be in trouble if I were judged and found lacking during that one tantrum in the grocery store!
