Remember how you gushed over your baby’s first words and first steps? How you took tantrums in stride (mostly) because you knew they were part of being two? It’s time to apply that amazement to the teen years because those babies are still incredible; they’re just navigating being teenagers instead of toddlers. That’s what it means to be pro-development; you cherish every stage. Instead of first foods, your current “baby book” can record awesome teen milestones like first thoughtful argument about politics or first deep friendship. Celebrate the stages and keep helping them grow.
