Though I cannot attest to the extent of helpfulness, Jerry let Lucy help him build a desk. She was a very proud building baby when she was done. And I did the dishes alone. I call that a good day.
"Let's have a break before we begin."
"Which one is it?"
"Righty - tighty, lefty -loosey... hey! Lucy. hehehe" (insert Grandpa Rod's chuckle)
"Dad? Where's my screw driver!?"
"I'll just use these keys instead"
"Gah! Not enough screws!"
"I'll let you help me Daddy."
(Did you wonder why her turtle neck is on backwards? It's because Daddy is as good at dressing babies as babies are at building desks.)
