6 week fussiness & growth spurt!

Britt. • I`m going to lay it all down.. I`m 20, in a long term relationship; I`m trying to conceive!
My son is six weeks old as of last Thursday, and Friday of this week he decided he was going to be really fussy which is extremely unusual for my son. He usually sleeps almost completely through the night and never cries! But recently for the past week he has been crying lots around the same Time every night and just wants to constantly eat. He will fall asleep about 9 PM and wake up around 11 wanting to eat for at least an hour! Is this fussiness going to subside soon, the breast-feeding doesn't even bother me it's the fussiness that drives me nuts! He will just scream on end until he can feed and then pulls off and screams more I really feel like I'm not getting a break!
