Signs on the roads and in the great outdoors can serve as wonderful mindful parenting cues. A common sign is the "No-U-Turn" sign, the one generally represented with the big "U" and a diagonal line cutting across its center.
Today, when you see this sign, take an imaginary U Turn with your life, going back in time to the point when your child first entered your life and imagining that it had not happened. As you're driving or walking, pretend that you are where you are but without your child in your life.
Life easily could have turned out this way. Breathe deeply and slowly and notice your feelings, whatever they may be. Just sit quietly and observe your feelings.
Later in the day when you are with your child or speaking with or thinking about your child, juxtapose the moment of being present with your child with one you had imagined earlier in which your child had not entered your life. If you are able, hold both thoughts in your mind at the same time.
This child
Like magic
Appears before me
