i triesd with Ewan but couldn't do it, he was screaming and i mean really screaming, so i tried picking him up calmin him and then putting him down and doing the patting on the back and shhh shhh shhh or picking him up again if he got really upset.
I dont think it is fair to let a baby cry like that, they dont understand, all they are wanting is comfort, reasurance, food, warmth, they cry for a reason they do not know annoyance or spite.
once you've ruled out all the reasons why they could be crying all you can do is offer reasurance.
