First Year Milestone Tracker & Red Flag Checklist

If you've ever Googled "is it normal that my baby…" at 2 a.m., you're not alone. The first year is full of incredible milestones—rolling, sitting, crawling, those wobbly first steps—but it's also full of questions. Is that head tilt something to worry about? Should those thigh folds look uneven? Why does everyone keep saying tummy time matters so much now? This checklist walks you through every major milestone window in your baby's first year, breaking down what's typical, what deserves a second look, and exactly when to loop in your pediatrician or a specialist. You'll get clear, jargon-free explanations of the WHY behind each red flag—not to scare you, but to empower you. Because when you understand how your baby's body is developing (like how hip sockets form during tummy time, or why slouching in a high chair isn't just about comfort), you can catch small things early and advocate confidently. I'm Kaitlin, and I've spent years helping parents decode early development—from the biomechanics of a proper crawl to why that one side always looks a little different. I created this checklist because I kept seeing the same pattern: parents who felt dismissed when they raised concerns, or who didn't realize a small asymmetry could signal something bigger. You don't need a degree in pediatric PT to feel confident. You just need the right framework, the right questions, and someone who speaks parent, not textbook. Whether you're tracking your three-month-old's neck strength or wondering if your nine-month-old's crawl looks "off," this is your roadmap. Clear milestones. Real red flags. Zero guilt.
