Oh ya, ALL the time! I'm singing about food, diapers, diaper contents, baths, toys, etc. I make up songs just to make up songs. I sing about something my little one is doing - earlier today it was something like "rolling over, go baby go, rolling over, because she told me so....." some of the songs I sing are just so stupid I don't want to repeat them :LOL The little ones like them though!
