Mine have all done it (7,5 and 3) and we just have to know when to call it on a hole. I try to reinforce some rules (like don't pick up the ball and stay off the green when it's someone else's turn) but others you just have to let go int he interest of sanity and time. Also, DH and I usually don't plan on all of us golfing. So for the 5 of us, we only pay for 3 or 4 assuming that one of us will team up with the 3 year old and another might team with the 5 year old (although now he's getting to where he wants to do it himself). If we all 5 had balls and putters, we'd be there forever by the time we help each of them.
