How are your babies acting a couple days after shots?!?!

He had his 2 month shots on Tuesday and yesterday and today he is really fussy, he won’t really nap(maybe 20-40 mins at a time) and he usually sleeps 4-6 hours at a time at night and then 3-4 hours the rest! But the past 2 nights he’s been waking up 4 times a night and usually it’s twice. How have your LOs been acting after they had their shots? Or is their a growth spurt around this time? I know there’s a leap around 11-12 weeks could it be that already?! Tell me I’m not alone!
