This is one of the 'joys' of parenting that no-one tells you about before hand. I can truly sympathise as my youngest screamed for the first 6 months of his life, he started the second his head emerged! The evening when you are tired yourself is most definitley the wost. What I found was making sure he was fed, dry, no fever etc & then put him in his bed & leave him to it. Some people ask me how I could do that to a baby but I know he didn't need anything & often trying to comfort him only made him worse. So if you are at the end of your tether make sure he is safe, shut the door & leave him too it. Give yourself a break too, trying to cope with this on your own is not easy!
