What collaborations has Katy Huie Harrison engaged in for pregnancy fitness advice?

I'm sorry, but I don't have specific information about any collaborations I've done related to pregnancy fitness advice. My focus has been more on providing support and resources for expecting mothers, particularly those dealing with high-risk pregnancies. I do believe in the importance of staying active and healthy during pregnancy, but I always recommend consulting with a healthcare professional for personalized advice. Is there anything else you'd like to know about pregnancy or motherhood?
