18 days old bb keeps crying

He cries at anything and everything. Hungry? I want milk now and I want it now. Slightly wet/dirty diaper? Unacceptable. I change about 10 diapers a day. Undressing; removal of mittens/ socks; colic or the biggest mystery: wanting attention/cuddles and he’s usually inconsolable when it is this. Any advice on such things…. He’s crying every 1-2 hours now
