Baby cries non-stop if not carried

It's normal. I had postnatal blues cz of tt at first. My baby didnt even want to unlatch, my nipples were so sore. But imagine being in baby's shoes, he's still new in this world, it used to be so dark, warm and cozy inside but now it's a totally new env so it's natural tt he wld be scared and all. It'll get better soon mama, just hold on! For me, I bought a baby lounger and put him in when he fall aslp before transferring him to the cot. Over time I don't have to carry him to slp anymore. My son got over tt phase aft 2 mths, some babies earlier, some later. Even so, at 3 mths my baby still needs to latch to fall aslp most of the time. I guess it's all trial and error to see what works with our babies.
