Happiest Baby on the Block?

I was struggling with Meili being really cranky whole of last week and found the book 'happiest baby on the block' a big help. It says to Swaddle, shush, swing, side/stomach lay, suckle - I was already wearing her most of the day but she would get upset in the evenings and refuse to latch even though I knew she was hungry and tired. Now I got this thing going where I lay with her on her side and pat her back firmly to the rhythm of my loud chanting of an American Indian war cry. She immediate quiets and starts sucking haha.
