There is also a stress release technique my kinesiologist taught me that is both simple and effective that you can use to help your child:
Place one hand horizontally across your child's forehead, gently cupping your hand; Cup the other hand across the back of your child's head, horizontally and in vertical alignment with the hand cupping the forehead. Do this for at least five minutes or until your child is feeling calmer.
This technique actively and gently releases both past and present stress/es/ors through the energy points located at the front and back of the head.
You can you use the technique on yourself but works best when one uses the technique on another, especially when performed daily.
*Edited* Oh and to help fretful babies, simply cradle / cuddle bubs and create a circuit by grounding both feet on the floor with your knees slightly higher than your hips, and then call on your chosen deity/deities to channel the baby's stress into the earth through your body and out of your feet. Keep the feet planted until baby is settled.
No one in the world can alter truth. All we can do is seek it and live it.
