He just wants to be held all the time!! Help!!

Any moms had a baby who just wanted to be held ALL THE TIME? My son is 3 months old and he literally cries non stop unless I’m holding him while walking around the house. Like I can’t even just hold him while I sit there. I have to physically be walking around for him to not fuss and cry. He’s been like this since he was born pretty much. I try feeding him, changing him, putting him in his swing, putting him in his bouncer, his Boppy, tried putting on cartoons for him, giving him gripe water, etc. I’ve tried everything and I just don’t know what’s causing him to cry so much. He just wants to be held!! And I don’t mind it sometimes but other times it’s really hard on me because I can’t even eat unless he’s napping. I can’t get ready for the day, can’t clean house, can’t do anything really because he just wants to be held. And I’ve tried putting him in those sling things and he hates them!! When does it get easier? Or what else can I do?
