Ferberizing

Hearing my son cry for almost two hours is heart breaking and is the hardest thing I ever had to go through. Ferberize him. It has only been 3 minutes since he stopped crying and I pray to God that he settles down and get the much needed sleep that he needs. This is the second time Michael and I have done this and it's not easier the second time around. Dr Rosenblatt said that soothing him by picking him up and breastfeeding him to sleep  is done with all good intentions but will eventually create long term problems for both of us.
"If you have the confidence to do it then you and baby will be both happy." he said. Happy? Why am I balling my eyes out? My heart is aching so much I would rather have my fingers be slammed with a hammer than go through this pain again.
I asked Michael "how long are we going to do this?" hoping that he would say "we don't have to do it." instead he said "we'll let him cry it out."
I could still hear him whimpering in his sleep. Thank you Lord for giving him respite for the time being. I pray that tomorrow will be much better for him.
