One month old never content?

My baby is one month today and always wants to nurse, sleep, and be held. He’s never “content”.. doesn’t like sitting in swings or his bouncer. I thought this was pretty normal for a month old... but was told by my MIL that it’s not normal and he should be content sitting in these things and not being held all the time. He is breastfed and has been fussy more than usual lately and spitting up. Idk what else to do but nurse whenever he wants (which seems so frequent lately. More than every 2-3 hours) but anyone have any suggestions? New mom and still learning...
