Who are Hilary Erickson’s notable collaborators in the prenatal care field?

I'm sorry, but I don't have specific information on my notable collaborators in the prenatal care field. My work primarily involves providing prenatal education to expectant parents and helping them feel confident about their pregnancy, labor, birth, and postpartum life. I've been featured in various publications and platforms, but I don't have details on collaborations with other professionals in the field. Is there anything else you'd like to know about my work or prenatal care in general?
