8 week old crying for 3 days straight!

Tracy

Help! It seems like nothing will soothe my baby. He will be eight weeks in a few days and has been crying on and off for three days it seems. No position I hold him in helps him, feeding him will satisfy him for a few minutes but then he’s crying afterwards again. He will nap for a little bit and then wake up crying. I have no idea if this is a growth spurt, gas, colic, it is awful. He doesn’t have a fever, and he still has plenty of wet and dirty diapers. He is constantly sucking on his hands and my shoulder, but I think he’s too young to be teething. At night I have to nurse him to sleep in order for him to sleep at all. During the day has been brutal. Any idea or suggestions? Thank you so much in advance.
