Hi, I'm so glad you're here!
Hi, I'm so glad you're here!
Hi! I’m Cierra Crowley, MSN, APRN, CPNP, and Founder of Bite Sized Wellness
With over 12 years of experience in pediatric nursing and as a Board-Certified Pediatric Nurse Practitioner, I am deeply committed to helping families build healthy, confident foundations during early childhood.
My career has spanned pediatric intensive care, obesity medicine, pediatric nutrition, and preventive + community health. Through these experiences, I saw a common thread—so many of the struggles families face could be eased, and often prevented, with earlier guidance and the right support.
As a board-certified pediatric nurse practitioner, I began my parenting journey blindsided by all the realities of motherhood. I’ve lived the realities behind the medical advice—long nights, worry over every fever, choking anxiety, and the constant question of whether I was doing enough.
Even with years of pediatric experience, motherhood changed how I understood health. It taught me that raising healthy kids isn’t just about medicine—it’s about connection, confidence, and feeling equipped to handle whatever comes your way.
As I tried to navigate breastfeeding, reflux, colic, unsuccessful sleep training, starting solids, tantrums, picky eating, sick days, and school/work dynamics, it became clear: parenting is just… not so black-and-white.
And I realized: there should be a handbook for this!
That's what inspired me to create Bite Sized Wellness—a space where parents can find trustworthy, evidence-based guidance rooted in both science and real life. A resource I wish I had when I was first starting my parenting journey. You can use this to find some peace, clarity, and hopefully some confidence to trust your gut as a parent.
I leverage my specialized training in pediatric care, pediatric intensive care, infant and toddler feeding and nutrition, and pediatric CPR + First Aid education to help growing families thrive. I pride myself on offering a variety of educational classes, online resources, and one-on-one coaching that can be personalized to meet the unique needs of your child, your family dynamics, and your lifestyle.
My Mission
At Bite Sized Wellness, my mission is to equip parents with practical skills, expert guidance, and everyday confidence to nourish, protect, and raise healthy kids - from first bites to first aid and everything in between. Every family deserves to feel calm, capable, and supported in their parenting journey.
Because when parents feel equipped and supported, kids thrive—and that's where lifelong wellness begins.
My Approach
Evidence-Based & Reliable
Every resource and service I create is grounded in current pediatric science and clinical best practices. While your pediatrician is an essential partner in your child's care, they aren't always available when questions pop up at 2 am or on weekends. And we all know that a quick Google search can lead you down a rabbit hole of conflicting and frightening information. I'm here to bridge that gap—offering bite-sized information and guidance so you can feel confident in caring for your child.
Empathetic & Non-Judgmental
Parenting today comes with an overwhelming amount of pressure and comparison. Add in rushed pediatrician appointments where you might feel like your concerns are brushed aside, and it's no wonder so many parents feel alone in their worries. As a healthcare provider and a mom who has been there—up at night wondering if I'm doing enough—I get it. This is a safe space where your questions are valid, your concerns matter, and there's zero judgment. Just real support, parent to parent.
When families face challenges that are out of my areas of expertise or that require collaboration or, I believe in a team-based approach and will refer to them as necessary. I work closely with trusted professionals across pediatric medicine, therapy, and nutrition to ensure every family receives the most complete and compassionate care possible.
I’m honored to serve families in the St. Louis area, as well as virtually across the U.S.
When I’m not working with families, you’ll usually find me chasing my three kids outdoors, cheering from the sidelines of a soccer game, baking sourdough, or enjoying a cozy pizza night at home. I’ve been a CrossFit athlete for over a decade, I believe all foods can fit in a balanced diet (except pineapple on pizza!), and I’ll absolutely sing along to any song—even if I get the lyrics wrong.
