Every night before I put the kids to bed, I tell them that I love them million billion trillion and kiss their heads.

I go back into my son's room and demand to hear the "Breakfast Report" from him, sometimes in a silly voice.  Mommy tells him what we're having for breakfast, and I ask him, and then he tells me.  It's silly, but it's become an important nightly ritual for us, and I highly recommend it :)
