Background: From Social Media to Book Publication

While weaning is a crucial period for a baby's growth, many families experience anxiety about whether they are proceeding correctly or if their baby is getting enough nutrition. The author, Aika, a mother of three, re-studied diet and nutrition after experiencing her own health issues and obtained an advisor qualification. Based on the WHO's concept of "complementary feeding," she began sharing recipes on Instagram that busy families could follow. Her practical content resonated with many, leading to a following of 98,000 (as of June 2026).

Her desire to share her message of "making weaning easier while ensuring babies receive essential nutrients" in a format that more families could access led to this book publication.

Author's Comment

"I want weaning to be something that can be made more easily, but I also want babies to receive the nutrients they need." I created this book with that thought in mind. The diet from birth to age two is said to build the foundation for a child's lifelong health. I hope this book will be an opportunity for moms and dads who feel anxious about daily meal preparation to relax a little and enjoy their child's important weaning period.
