No Sleep for Mom

well its 1:16am and I am trying to let Jaxson "cry it out" but after a 12pm feeding and now over an hour of crying. I am not sure that I am up to this. I was hoping that after the first few days he would cry less and less, but it does not seem that way. It so hard to sit here and listen to him scream when I know that if I nursed him he would go right to sleep... OH SLEEP I have been up for 18 hours now!
