Help!!! 7 week old...

My extremely fussy 7 week old (tomorrow) used to at least go down without a fight for bedtime but this past week screams bloody murder although he is obviously tired. I have tried putting him down earlier, bath routine, etc... He has been super alert and active since he was born and does not sit still, even in our arms. It's been extremely frustrating attempting to soothe him during the day but at least I was able to put him down for the night easily...now that's a struggle. Growth spurt? Ideas? Advice? I'll take anything... TIA! Pic for attention..
