Growing a garden provides 'plenty' for your home. If you grow a garden you can occasionally find it overrun with weeds. This usually happens if the mosquitoes are bad, you've been on vacation, or it has been exceptionally humid. This year the weather has been pleasant and I have managed to keep up nicely.
Kid's on the other can get out of control for any number of reasons. Maybe you've been distracted by work or just tuning out while they play too many video games. Sometimes its because of relationship discord and splitting with your partner. Sometimes its negative peer influence. That can creep into your home like cockleburrs into your garden. Once its infested it is tough to root out. Whatever the reason your kids are acting up they can get to that point where the rules aren't working anymore. Like your garden it can be overwhelming trying to get back to parenting again.
When I am reclaiming my garden. I can say "I'm gonna go clean that garden top to bottom," the reality is that energy doesn't last long. Usually, I do better if I pick a section and just work a little bit. Maybe the buttonweed needs to get cleaned out of the beans. Once, I am started it usually goes fairly well and I do a little bit more than I planned. The main thing is that I have gotten started. The hard part of weeding is pulling the weeds and making sure you don't pull the plant with it. If you try to work to fast or grab too many weeds at once you end up damaging your plants.
It's the same with kids. Pick a behavior and focus on that. Try to eliminate all the negative behaviors at once and you will end up making the kid feel like you just want to get rid of them.
Like weeding you still want to nourish the plant and cherish the produce.
I'll let you finish the metaphor.
