I want to compliment Game Golf's customer service. I wrote to them about the issue and they had me send them some log files from my computer. From these, they were able to upload my three rounds that went missing.
One course appeared to be missing graphically from the desktop version (GPS tags appear, but not the course imagery). I told GG support about this issue less than half an hour ago and it's already fixed.
I'm still going to try to upload my next round via mobile to see how that works. I might have to force myself to go play tomorrow or something
Overall, I'm impressed with how GameGolf handled this.
I regret that I quit playing golf when I had kids. I did buy them a cheap set when they were young. My daughter was never interested. My son was interested but time, money, general sense of family obligation, and fear of slow play kept us from playing more that a couple times per year, particularly after a golf buddy moved away. My son has atrial flutter, a heart tachycardia problem, that made him quit playing soccer after his sophomore year of high school. Three ablations were not able to fix it and he relies on medication to control it now. He decided to play golf instead of soccer and now loves it. He is much better than I am and will play golf at an NAIA college this fall. This finally got me back on the course over the last 3 years and he is my main playing partner for now.
A younger friend of mine has 4 kids under 12 years old. The older 2 are into golf and I end up playing with them sometimes when I play with my friend. The younger 2 also occasionally play or at least ride along. We usually play an adult/kid scramble on Sunday nights when the course is not crowded. It can be a lot of fun as the kids aren't too bad, but certainly not young Tigers either. Beginning this week I am playing in a Saturday night 2 man scramble league with one of the kids my partner. I don't even know which one it is yet as I just agreed to it blindly. I hope it is the 10 year old as he a slightly better swing than his older brother. It will be interesting to see how that works out.
I sometimes wish I had my kids on the course like my friend does.
I started golf with professional lessons around the age of 11 and have been golfing ever since. Most of the stories with kids involved is of me. However, I was also a rules marshal in my home course when we have junior tournaments there so have seen some kids who have become very impressive amateurs and even one or two who have become pro's.
Regarding clubs, see if they can use the same clubs provided it doesn't affect their swing. If not, either consider getting shaft extenders or look at clubs where you can change the shaft with a tool and then replace shafts as necessary. Not cheap, I admit, but might be necessary. Definitely consider the younger child getting hand me down clubs from the elder child provided the specs fit.
