Ava, an early childhood professional, shared this after her training:
“I looked at the baby in my arms and saw that he was looking right at me. He had always been looking at me. I suddenly realized that all the babies I had fed over the years were looking at me and that I had missed those opportunities.
I felt so sorry to have missed those moments and vowed to never miss another. Thank you for creating this training that helped me to see this.”
