Is this normal after 8 week jabs?

[Suzysuz]

My son had his 8 week jabs (he was bang on 8 weeks) on Tuesday morning.
During Tuesday and Wednesday he was okay, slept quite a bit but drank and nappies okay.
He was fine yesterday morning but really fought his day naps so was a bit shorter on sleep, he also had 3 slightly runnier nappies. He almost suddenly turned in the evening and wouldn't take his bottle (mixed fed), crying in discomfort. We managed to get him to sleep eventually.

Today he's the same, moves between generally okay to crying in what seems to be discomfort. I move between upright jiggling, sling and boob to try settle him.

Is this just the normal path after the jabs and rotavirus vaccine? I was prepared for the same/next day reactions but this 2-3 day delayed reaction has thrown me and am a bit worried (PFB!)

Expect him to have runny poo for about a week after rotavirus. Low fever is normal too so make sure he's not bundled up too much. My DD always needed to be held during the night after her rotavirus.

Sounds perfectly normal.

Thanks
I was prepared for the temperature, just the 2 day-delayed unsettling/crying took me by surprise.
Just got him settled on me, he looked up and gave me a big smile making me well up but better this than the illness the vaccines prevent (that's my mantra during the crying anyway!)
