i can relate to this

kyle's going through a few of these and now i understand why... :)

really enlightening stuff from baby center.

excerpt: "Question: Why does my toddler sometimes reject my affection?"

a few reasons why:
> He's had a bad day.
> He's recovering from a tantrum.
> He's upset with you and doesn't know how to say it.
> He may be going through an "independent" phase.
> He's in a Daddy-favoring (or Mommy-favoring) phase. (more on a Mommy-favoring phase which sometimes makes aishi jealous)
> He may not be the touchy-feely type. - this i doubt with kyle. :)
> He isn't feeling well.
> He's experiencing real anger or distress — and acting out inappropriately.
