Awww hun, you're doing a great job. Your last post there struck a few chords with me with regards to your friend letting her little one cry it out and thinking you should do the same. Stick to your guns. I read somewhere that crying it out is a short term gain for a long term loss. What we are doing is a short term (loss of sleep!!) problem for a long term gain!
I'm sorry to hear that DH isn't more supportive.... just keep reminding him it won't last forever.

Keep at it hun, your little man will surprise you one night by sleeping a long stretch and then you'll freak out and keep checking to make sure he is ok!
