Congrats on your life, my friend. It's one to be proud of and one which a lot of people will envy.
How old is your son?

Do you work for the same company you did prior betting? Is there an option to become a self employed developer and work on a freelance base for other companies. Just thinking out loud of course, but that would give you some kind of freedom, and also the power of change so you won't get bored out too often. And perhaps you would be able to combine it with betting or other sources of incomes.
Betting isn't the most secured income and I wouldn't recommend it to only rely on that when you have a young nice familly. Just my two cents of course ;-)
