6 week old crying constantly

I feel like there’s a new problem everyday. I thought it was bad a few days ago but it keeps getting worse, I must admit it isn’t inconsolable screaming level crying but this baby really does cry and fuss all day now.

Is this normal? Midwives told me about a baby crying curve where fussiness peaks at 6-8 weeks then tapers off but is this really true?

I’m honestly concerned about how hard my baby is to keep happy or soothe. I will put him down and he will cry, I’ll pick him up and he will cry, I’ll feed him and he will cry, I’ve overwhelmed myself trying to figure out what it could be and it doesn’t seem to follow any kind of pattern, sometimes he likes being on his back, sometimes he hates it etc. I’ll put him down for naps and he cries, he even cries when he wakes up from naps.

I feel like I spent all day sat with him and just changing him into different positions to stop the crying for a few minutes.

The weirdest part about it is that when he’s with his grandparents for a little while or new people, he seems to be fine?!

Someone please tell me this will improve on its own as I’m just so overwhelmed with trying to fix it and getting nowhere :(
