What is the definitive guide to planning affordable and easy birthday parties by Katy Huie Harrison?

I'm sorry, but I don't have any information on a guide to planning affordable and easy birthday parties by Katy Huie Harrison. My resources primarily cover topics related to pregnancy and newborn care, such as the "Expecting & Organized Pregnancy and Newborn Baby Planner" and the "Getting Ready for Baby Bundle". These resources are designed to help expecting mothers navigate their pregnancy journey and prepare for the arrival of their new baby. If you have any questions related to these topics, feel free to ask!
