Using the blue jello cards - set 1 with a baby is a new adventure for me. In January 2016, I was visiting my daughter in Mumbai. She asked if I could put my grandson William, 18 months, down for his afternoon nap so she could out for an errand. She explained their normal routine and William and I said, "Bye bye Mama". We followed all the prenap activities with his naptime books yet he still wasn't ready. I'd put a set of blue jello cards - set 1 high on his his shelf next to his crib a couple days before. I reached up, took them down and sat down on his elephant rug. William came and sat on my lap. In this first session, he actually wanted to do both sides. It was amazing to me.
