Ways to make him sleep..

Kevin and I no longer accompany Dillion to sleep at same time.. It either me or him with Dillion.
Yesterday Kevin merely took 15 min to make Dillion sleep for the night and I was impressed and i asked him:

Me: How you make him sleep?
K: Normal ways lor.. hug him the way you hug him then sing a song, kept quiet then sleep.
Me: So easy meh.. ok i try to sing song next time.

When it was my turn today.. I sang Barney's "I love you" "Airplane" song.. and D still refused to sleep. Instead he kept saying "More More More".

Either Daddy's singing is too soothing or too awful or perhaps my singing is too good that he want to hear more ??
