Please tell me this is a growth spurt

Ma

My LO is about to turn 9 months on Wednesday. For the last week she has been miserable- fussy all of the time. She's usually super chill so its really strange when she acts this way. Now she won't nap unless I nurse her. But then she doesn't even nap that long or I make the slightest movement she's wide awake. I don't mean to be annoyed but it's really frustrating because I'm a teacher back at work and I count on her nap times to get work done. She was on me ALL day yesterday nursing. I'm trying to remember she won't always be this way and to enjoy her wanting to nurse but I just had to vent right now because it's been nonstop today.
