NO WAY are you alone!!!!!!!!!! My first son was EXACTLY that i could have written your post myself, What am i doing wrong?? was my thought,
And how come younger people seem to be doing better at this then me???? I thought that I would be a natural and it would not be that hard!!
My son had Colic and nothing i mean nothing we did would help him!! He just grew out of it. I was told by 12 weeks they should be right!!! Luckly he was bout 9 weeks and totally changed. I am not saying that he was perfect but the daily screaming stopped!!! This might not be your bubs problem just telling you my story.

Goodluck and i hope things gets sorted out for you and your bubs soon!!

It does get easier and better I promise !!!
