Vaccines changed baby's demeanor?

I know it could be a total coincidence, but DD had 2 vaccines at her 6 month appt on Saturday. Since then she's been impossible to nap and cries every 30-90 minutes at night. Not just fussing, but inconsolable screaming cries. She hasn't eaten at night, and has been basically STTN for well over a month now, but I even had to feed her last night to calm her down, and that was on top of at least 5 wakings.

She is usually the happiest, smiliest baby, but now all she does is cry and want to be held.

I know it could be teething (though I don't see anything, and Tylenol didn't help calm her) or a growth spurt. But just wondering if anyone else had their baby's entire demeanor change after a vaccine. I never experienced this with DS. Any ideas?

It definitely could that be since that was only three days ago. With my kids tylenol always helped, though.

I'd call the doctor so they can tell you exactly what symptoms you can expect and for how long, based on the specific vaccines she got. Or they may tell you to bring her in just to check it out. Either way you may feel better about it.

Not related to vaccines but dd2 did go through a few similar phases. My first never was like that but my youngest was really tough at times. She will suddenly stop napping unless she's held and i really work at it and she'll just generally be super fussy. Usually lasts a few days but sometimes it's been a week or two before she snaps out of it. It definitely seems to come out of nowhere and doesn't seem to be teething or anything like that.
