Hi A.,
I'm in Charleston, where are you? I was reading through some othr responses, and can I suggest something else? I cannot for the life of me understand why you'd allow your baby to cry for you and just do nothing to comfort him.(as others have suggested) He IS crying for a reason. He needs you! At 6 months old he likely still needs to nurse often and at this age could be having a growth spurt. Ignoring your child's needs by doing nothing will not solve anything. This is a precious time and they grow so fast; follow your instincts and give him the nourishment and comfort he deserves. I would argue that Baby Wise and the Ferber method border on neglect.
