This one just had to be recorded for posterity. Somehow the boy got the words diaper rash and bubble wrap confused. I guess the syllables and emphasis are similar. So if you show him this stuff, he may well exclaim, "Diaper rash!"
You could learn a lot if you let the boy read to you. For instance, we've learned that G is for lamb, O is for lemon, W is for food (watermelon), and Z is for animal.
