It was such a pleasure presenting at the Arizona WIC Breastfeeding Peer Counselor Conference last week! I was also so excited to meet my USLCA colleague, Jessi Gomez, (pictured here) in person for the first time! A big thank you to Jessi from Pinal County WIC and Soraya Franco from Pima County WIC for inviting me to speak on such a fun topic, “Breastfeeding Beyond the Newborn Stage.” I hope your WIC teams enjoyed a meaningful day of learning and connection! 😊🙏🩷

We received this message from a client the other day, and it was so sweet that we just had to share! As I read this message, I was so humbled to know that our care touched her and her family so deeply. At Thrive Theory, our goal is to provide the support and guidance your family needs to thrive, and messages like this remind us why we do what we do every day. ❤️

Are you watching your baby's Hunger Cues?

Rooting, Hands to Mouth, Opening & Closing Mouth, & overall Increase Awareness are all early hunger cues that babies give us in order to know it is time to offer them breast or bottle. Some babies show more of a single type of cue, whereas, others might show all of them, so this is another opportunity to learn your baby's preferences.

If you find that feedings are an especially stressful time, question if you are waiting too late. If you wait till your baby is crying & fussy, it can make for a particular difficult feeding session.

As always, Thrive Theory is here if you are looking for any extra assistance in your feeding journey!

Are you concerned that you’re not making enough milk for your newborn? Nature has our backs! Your nutrient-dense colostrum is the perfect first food for your newborn’s tiny tummy. It’s supercharged nutrition in a teeny package.

Because it’s so thick, hand expression with good technique is usually a more effective way to express colostrum than pumping. And guess what’s even more effective at transferring colostrum than hand expression? A breastfeeding baby! So no need to “pump to see how much colostrum baby is getting.” — it’s a trap!

Baby will need to eat frequently in the early days, and that’s totally normal! Cluster feeding can be intense, but on its own it does not mean you have low milk supply.

If you’re ever unsure if your baby is getting enough to eat or if you just need some extra reassurance, that’s what we’re here for! Please reach out to schedule an appointment!

Happy World Breastfeeding Week! Today’s video is a long one, but it’s well overdue! It’s honestly not easy for me to talk about my own journey into motherhood, which was unfortunately quite traumatizing but also blessed me with the most amazing child I could have ever asked for. Even though our journey didn’t go as I had imagined, I kept breastfeeding and pumping through it all, and I’m so proud of myself for every drop of breastmilk that I worked so hard to be able to provide for her! In honor of this special week and the wonderful perinatal support community in Tucson that has made me feel so safe and accepted, I wanted to take a moment to share my story with you and to explain what inspired me to become a lactation consultant.

📣 Thrive Theory is growing! Please join us as we welcome Antoinette Cornelius, CLC to the team! Antoinette will be offering home visits and telehealth appointments, and she is in-network with United Healthcare and Cigna. Take a look at her bio below and follow her at breastfeedwithantoinette to learn more! 👀

Antoinette Cornelius is a Certified Lactation Counselor (CLC) with a Bachelor of Science in Chemical Engineering from Arizona State University. She spent over a decade working in engineering consulting, where she developed a strong foundation in customer support, education, and communication.

After becoming a mother of three and facing her own breastfeeding challenges, especially difficulty finding quality support, Antoinette was inspired to shift careers and pursue her passion for maternal and infant health . She has been serving families as a practicing CLC since 2024 and has been training with Katie Cohen, IBCLC, throughout this time. In addition, she has been a Breastfeeding USA Counselor since April 2025, providing peer-to-peer support to families navigating their feeding journeys.

Originally from Willcox, Arizona, Antoinette is honored to be back in her home state after years of supporting her husband’s military career. Drawing from her experience working in male-dominated industries as a working mother, Antoinette has a particular interest in supporting families through the transition back to work. Whether you plan to return to work or not, Antoinette is most committed to supporting you to meet your breastfeeding goals.
