Time to get naked

I love it in the evening when I say to Cord, "It's time to get naked". He drops whatever he is doing and runs upstairs to the bathroom. He knows it's his bath time and he loves it! Lately he runs into the master bathroom. I guess that's because it's so big. For him it's almost like swimming. I also love how he smells after I rub him down with baby lotion and he is dressed in clean jammies. How old is to old for baby lotion? I hope it's not soon!
