12 month jabs

My son had his 12m vaccines 6 hours ago and he has sobbed on and off since. He won’t nap which isn’t like him and he’s exhausted.

He’s super rosey. No fever yet but been on top of meds. Is this a normal reaction?

He was fine with 8 and 12 week jabs but really unwel with 16 weeks ones. I was told he’d be ok coz he’s older now…
