Lynn's Comments: When my son, Aaron, was about two and a half years old, I enticed him into the bath, telling him he could have any colour water he wanted. I put a box of food colouring on the edge of the tub and he chose blue. I let him put a few drops into the water, and just as his blue bath was ready, the phone rang. The kitchen phone was right around the corner. I briefly talked to a friend as I listened to Aaron playing in the bath. I couldn't, however, see what he was doing.
