What they neglected to mention about baby-wearing:
#3 - Sometimes you don't feel like wearing your baby.  
Just bein' real here.  A lot of times I start out the day tired.  And to add more weight on my shoulders?... sigh.  I strap Sweet Pea on and in a few minutes, I feel pregnant again.  I bump into things.  I have limited agility.  BUT, long ago, the concept that I don't live by my feelings was
drilled into me.  I consider it one of the most valuable lessons
of my upbringing.  I may not feel like doing it, but I do it. 
Because it's right.  Because it's good.  Because it's worthwhile.
