I've got a different version too that I can share:
First, for those of you who practice Yoga, Meditation or anything that teaches belly breathing, I use a very deep belly inhale to help me produce a loud, long, powerful shhh. This long shh is doubly beneficial because it helps me practice belly breathing and also helps me stay calm. Also, since my dd doesn't sleep on her side as the pat/shh method describes, I lay one hand on her chest/upper arm and do a soothing stroke on her other side with my other hand (usually my left hand). I start the stroke at her shoulder and move down her body slowly as if I am guiding her tensions out her toes. I had a Yoga instructor that use to help us relax at the end of class by doing a similar slow stroke on our neck.
Does anyone else have alternatives to share?
