They are your kids, the balance is easy. Give them everything of your yourself. When they are toddlers you are their hero. Later during the angst stages you will get your time. "Grind" out the early time and who knows? Chores can be grinding the relic iron, getting you that new purple fully upgraded. Early on just be there, not in the same room, but play with them and engage them. Besides when they are at school later in life you will have lots of time. Enjoy being their hero, hopefully they awe never quits.
