DD uses them all the time too. In fact the other night this is the conversation between DD and DH.
DD: "Daddy, stop dilly dallying and let's go."
DH: "I'm not dilly dallying."
DD: "You are dilly dallying and we're going to be late."
DH: "You're the one who's dilly dallying."
DD: "Mommy!! Daddy said I'm dilly dallying, but he's the one who's dilly dallying." [DD to DH under her breath] "Dilly dallier!"
