Girls forget a good bit of compliments they receive but they remember every single insult. Speak gently, remind them they’re beautiful. Never qualify it.
When you bring home a new baby, make sure your older kid(s) hear you talking to it the way you talk to them: “I’m sorry Baby I can’t hold you right now, I’m going to play with Sibling.” It makes it a lot easier to tell Siblings that you can’t give them attention right now because Baby needs you. Less resentment, etc.
Practice not putting stuff off. If it takes 10 seconds or less do it now. Then move up to 30 seconds or less. Keep going up to ~3 minutes. Good example is putting away laundry or emptying dishwasher, etc.
Keep porn to a minimum. Never at school or work. It's normal to be curious but it's really not a healthy representation of sex. Porn is a business. It's designed to get you off, not to be realistic or educational. That's not the way sex looks or how you're expected to behave. Try O.school instead.
Date all kinds but marry someone who loves you for who you are, with whom you feel most yourself. Someone who will encourage you to grow more into the person you want to be. (And be good at encouraging them to do same.) Never fear or stifle each other’s growth. Celebrate it. Support it. Encourage it.
Reinforce this at every opportunity: “You matter.”
Kids respond to this message deeply, whether it comes from a positive source (parents/teacher/coach) or people who are only trying to exploit them.
Sometimes big stuff happens. Big good, big bad, big change. It will take some time to adjust. Maybe a month, a season, a semester or maybe a year or longer. Gear up. Psych yourself up for a difficult day/month/year. You can do this. Stay present, don’t get ahead of yourself or get bogged down in what’s done. “What if?” and “if-only’s” are not your friends. Be good to yourself and be good to others. Rest, nourish, create, have fun and keep the faith.
