Parenthood doesn’t come with a manual—and for many, it doesn’t come with a village either. TDB is a physician-backed and real-life tested community designed to support you through every stage of growing your family—from trying to conceive to pregnancy, newborn life, and the toddler years. Created by Dr. Sarah Bjorkman (OB/GYN) and Dr. Kurt Bjorkman (pediatrician), this is where evidence-based medical guidance meets real-life parenting support. Inside, you’ll find a space built for modern parents who want more than quick appointments and endless internet searches. Whether you're navigating IVF, preparing for birth, or adjusting to life with a newborn, you’ll have access to trusted information and a community that understands what you're going through. In TDB+, you can connect with other parents in the same stage of life, learn through structured courses, join live sessions and Q&As with doctors you trust, and access resources that simplify complex medical topics. This is more than content—it’s a place to belong. Many members join during one life transition, but stay as their family grows—because the challenges evolve, and so does the support you need. If you’ve ever felt like a 10-minute doctor’s visit wasn’t enough, this is where you’ll find answers, connection, and confidence in your parenting journey. -- Terms of Use: mn.co/terms-of-use
