I so know how you feel, i did anything to stop Abbi's pain as well, made me overanalyse her piercing crys. I would think she was in pain, but she wasn't once on the meds, it was a habit cry. Don't get me wrong she has a paci sometimes, but when it pops out she does not wake up. If it stopping the pain it is such a difficult decision, but are you sure he is pain, or just real upset as he wants the paci?
