With toddlers (or teens), first acknowledge the emotion. Then deal with the behavior.
Validate their feelings. Once everyone is calm, address the behavior and discuss consequences if appropriate.
My worst fear is that I will be unable to reach you when you’re in pain. All I want as a parent, what my whole job boils down to, is to be there when you need me. How can I help you?
Don’t be “too” sure of yourself. There’s always a chance you could be wrong, so be open to what others are saying and consider the possibility they could be right. They very easily could know stuff you don’t. Their experience could be a lot different from yours, so just be careful of insisting you’re right.
What I most want to teach you this year is that you can always trust me. I will always love you, take care of you and never harm you. You may not always like me, but you can always trust me.
Change “I need to” to “this matters because”. Instead of “I need to walk the dog” say “it matters that I walk the dog because he needs exercise and to check p-mail.” (Helps!)
Say it early and repeat it often, so that it sinks way down deep: There is nothing you could do to make me stop loving you. No mistake, no failure, no decision, nothing. There is no hole so deep that if you fell into it I wouldn’t climb down to help you out of. I love you no matter what.
Sex: There's no single way to do it "right" but there are lots of ways to do it wrong. Not being respectful and tender towards your partner is usually at the root of "wrong" ways to do it. Also, there is no rush. You may think all your friends are "doing it." They're not. Take your time.
We don’t always get what we want. Sometimes we have to wait. Sometimes we go without it. Sometimes when we DO get what we wanted it looks different than how we imagined it would. AND IT’S OK. We’re ok. The world keeps turning! That’s a huge lesson and a valuable one. Practice “pushing the snooze button” on wants. Enlist their help. “I understand you want ____. Would this be something you could snooze or do without?”
Practice people skills: Firm handshake, introducing yourself, being courteous when encountering / being on receiving end of someone’s rude behavior, offering your seat (never sit while someone with gray hair, pregnant belly, any sort of injury or really anyone who is older or who works harder is standing.)
It’s best not to cuss but writing bad words is even worse than speaking them. Even in casual texting, etc. Always an asterisk in place of a vowel to avoid being rude.
Institute “Family Night” a screen-free night of games and fun and togetherness. Can use these times for conversations about things you want to address / teach. Maybe make theme nights and build around a lesson so it’s fun and enjoyable.
Continue through school years.
