Being a new mom is hard. Newborns don't come with a handbook.
I found that when I didn't know what to do, I would OM to clear my mind, reset and try to approach the situation with less stress and frustration. When baby is crying and she's full with a clean diaper and just needs some sleep, I would find myself om-ing in the rocking chair. And to my amazement, sometimes baby would just relax from the vibrations.
