It's true when they say, he who pays the rent, sets the rules. If you can afford to completely, finance all your children's needs, then you are given enough "leeway" to parent them. Freedom really comes with a price
Realistically though, you need your parents to watch over them while you work. Your best strategy is to work so hard and earn your parent's trust that you could stand by your own when they die
Right now with limited resources, have a heart to heart talk to whichever parent you're closer with, and present your problem. Have one room to contain essential things for you and your kids. Make that your kingdom.
