Learned in my childbirth education class this weekend that if you feel LOs movements predominately on the right side (Im with you there!) that its very likely because baby is in optimal position for birth. Baby's head would be down, turned slightly to the right, butt near belly button and so legs are kicking out to right? Hands too probably.
So consider it a good thig for now unless told otherwise? Though my right side could sure use a break too...
