That's awesome!! I remember loving when my kids got that skill down!! My daughter is almost good with drying her hair too - she is mixed and has my husband's hair, so it takes a round bruch and layering to do it right :).
Last night we were doing our household chores and my 7 year old asked me who was going to vacuum (since it was the week for my 11 year old to do it). I told him I was going to do it, no big deal. He then asked if we actually added steam mopping to the vaccuming chore, since it's only one room that gets vacuumed, and I said yes, but I would just do the kitchen. He asked me to do it himself! He got the steam mop out, put the water in, heated it up, and did a fabulous job! He was so proud of himself and so was I...awesome!
The best part, while he was mopping he decided since I was going to make him throw away his 3 foot tall box his new nerf gun came in and he didn't want to, he came up with a plan. He put holes in it, asked me to help him tie knots, and he made himself a backpack to carry his new nerf gun around :).
