Toddler fussy for almost a week after vaccines?

Amanda

My daughter had her 15 month boosters last Thursday. She had a mild fever for 24-36 hours, but has been fussy, clingy, and more tired than normal since the shots. I’ve never experienced this. I’ve heard MMR can take longer to cause a reaction. Anyone else experience this? She has little pockets of being happy and herself but 80-90% fussy. I’m worried 😕
