You can get into big trouble (with school and the law) even by fake / joke threats of violence (bomb threat, etc.)
No jokes or pranks that have anything to do with violence.

They can shower themselves if you install a hand-held shower head and install a suction cup wall-mount shower head holder lower on the shower wall. It’s easy to do and very cheap. They love it!
Start “home economics” school with them. Laundry, cleaning, cooking, how to change a diaper, comfort a baby, soothe a toddler, what's involved in caring for pets, budgeting for food, keeping track of maintenance schedules for humans, pets, cars and machines. Engage with guests, be a good host, etc. Know when and how to tell someone to GTFO of the house (racist or misogynistic speech, etc.) Every kid needs to learn the art and science of home management. Look for and point out examples in books and movies of good home science skills.

“A lot” is two words. (You wouldn’t write abunch as one word.)
“Its” is a pronoun like his or hers (you wouldn’t write her’s) The contraction “it’s” ONLY means “it is.”
They’re / there / their
When you feel hopeless that’s when you know it’s time to seek help. It’s a red flag in someone’s demeanor. Notify parents if you notice this feeling of deep despair in yourself or someone you know. Help really does help.
Go for walks together as a family before or after dinner. Sometimes we go for distance, sometimes we call them "safaris" and look for as many living creatures as we can find.
Look for answers where truth, laughter, kindness, beauty, compassion and love are found. (Not in outward appearances or illusions of perfection. Not in cynicism, apathy or destructiveness.)
Your body will go through all sorts of shapes and sizes. You’ll have times when you’re gorgeous and times when you’re awkward or frumpy. Whether you’re having a great hair day or sporting a face full of angry pimples, your looks have never and will never define your worth. (And nobody else will ever be defined by theirs.)
