Have a yearly “review” right before school year. Raise allowance as appropriate. If they want more money, they’ll have to take on more responsibilities.
Talk about how choices become habits. Habits can become addictions. Describe how pathways are literally dug into the brain and it's very hard to change them once those paths are made.
Toddlers fall... a lot. Most falls are harmless but sometimes bad accidents happen. Head injuries are scary because they bleed and swell. If bleeding doesn't stop within a few minutes or you can see it's a big gash, head to the urgent care. And remember if the swelling goes out (“goose egg”) that’s a good thing: Better out than in.
Putting up the Christmas tree the weekend or next after Thanksgiving, then watching Polar Express in the glow of the lights. Maybe the smell of gingerbread cookies baking too.
One of the most important things I can teach you is to help you learn how to deal with big feelings without resorting to destructive behavior or violence. Everyone on the planet will experience loss, disappointment, grief, heartbreak, betrayal, etc. Tools to deal with these feelings: counseling, journaling, art, music, exercise, meditation, breathing exercises, yoga, being in nature, talking with friends, joining a support group, movement like dancing or skating, singing, acting, anthropomorphic dialogue with your emotions, naming your emotions and describe how they physically feel in your body. Asking the emotion what it needs you to know.
A mommy-friend of mine gave me some good advice: "Count the wins." So what if you didn't clean the house, you showered! So what if she's wearing 9 different colors - she dressed herself! Great advice. So remember, especially on the difficult days - and there will be many: Count the wins.
Imagine hearing the apology you need to hear. Often times that really helps, even if the person never actually says it. It makes it easier to forgive and move on.
Encourage creativity, science and engineering: Make a craft station / work bench for projects. Fill it with all kinds of art supplies, engineering kits, tools, pegboard, etc. Stock safety equipment like goggles and make sure the area has good lighting. Lots of ideas on Pinterest, etc.
Venting is crucial but not always appropriate. Make sure you’re in the right place (no chance whatsoever of being overheard), the right time (take care of business first) and that the person you’re unloading on has the mental bandwidth to listen to you vent your emotions. Avoid interrupting if they’re busy, or not in a good headspace. You’ll know this because you asked.
Think about building a career. Take low-paying or no-paying jobs that will give you the experience you need to build it. It's not all about the paycheck, especially when you're young and don't have too many bills to pay.
