Parents often feel frustrated when their children don't "cooperate" — when they don't go along with the parents' stated intentions.
Today, no matter how your child behaves, take the perspective that your child is always cooperating with you — if not behaviorally then vibrationally. Children sense their parents' "vibes" and reflect back a similar vibration, often exaggerated in their behavior.
For example, if your child is impatient, ask yourself how s/he might be "cooperating" with you vibrationally. "In what way(s) have I been emanating an impatient vibe?"
If your child is resistant, ask yourself, "Am I being resistant in some way?" Look beyond the obvious and feel for an answer.
Fortunately, it works both ways, so that when you're feeling joyful, your child will "cooperate" with that, too! But depending on your established patterns of interaction, it may take some time for your child's behavior to reflect your positive vibration.
In the meantime, you can practice enjoying Well-Being unconditionally. :)
