When my son was 3 years old, I held him in my arms. With amazement, he looked at me and said, "Mommy, you're carrying me!"
I have Charcot-Marie-Tooth disease and, because I used crutches, I had never walked while holding him. Now, we were standing in a swimming pool. After explaining to him how the water could support me, he suggested we fill our house with water so that I could always walk.
