Newborn Cries All the Time

I am a recent new mom and have a three month old baby. Things were going good until now, he cries all of the time, that is until I pick him up. He refuses to lay in his crib alone and will cry and cry until I pick him up. I check his diaper, check everything and there is no problem, until I lay him back down. He is in total control and I don't know what to do about it.
