7 weeks today. fussy and won't nap. growth spurt or???

Sam
Hi everyone. Ok so my 7 week old was napping well now he's only napping 1/2 hour here and there and is super fussy and cranky. He needs to be held all the time walked around the house or fed in order to be calm. I end up feeding him every 1-2 hours because he won't calm down. Sometimes he'll eat for  5 minutes and pass out- until I put him down then he wakes up super fussy! And normally he's super super great & happy. Is this a growth spurt or just what happens??? I'm a first time mom and am feeling like I'm doing something wrong.... last week had no problem smoothing him and now nothing is working. Advice, suggestions, feedback welcome! 
Thanhs in advance.
