I have had 5 babies. All of them have been practically attached to me from birth. Seriously, as in only put down for nappy changing and while I went to the toilet in the first 6 months and then co slept right up until they were 2 or 3.
They all cried like their hearts were breaking when I put them down, and settled as soon as I held them, so I held them. For their sake as well as mine because the crying had a real physical effect on me and made me feel ill.
I was convinced that all a crying baby needed was to be held. Because, you know, it had worked for all 5 of mine!
Then my sister had a baby that cried and cried. She said she had to put them down because the screaming drove her crazy. I told her all about the magic of a wrap and how she just needed to hold him. I went round to show her to do the wrap properly, because if it wasn't working she must be doing it wrong. (I know, I know, I was a dick!)
Well guess what. The baby was put in the wrap and he screamed and screamed and I paced and rocked and shushed etc, and he screamed for fucking hours.
He was a screamer right up until 3 years old and is still a bit of a screamer now that he's 5.
Moral of the story is that all children are different. Some babies cry more than others. Some babies are more demanding than others. Some for medical reasons and some just because.
Also, I learned the lesson, that as experienced as I was, when it came to someone else's baby I didn't have a clue. My sister knew best and learned that a quiet dark room and 10 minutes of screaming was the only thing that got him to sleep and saved her sanity.
Do what you have to do.
