5 week growth spurt/fussy baby?

Has anyone noticed their baby extra fussy at 5 weeks old? Someone has taken my great sleeper and happy baby and replaced her with a fussy, cat napper today.

Looked online, there are tons of articles about a major growth spurt both physically and neurologically at 5 weeks. Said it’s totally normal for babies to be extra fussy and hungry this week. She hasn’t napped for longer than 1 hour today, and she is completely fighting those small naps. Anyone else?
