How was your baby after jags?

Kayley • 24 years old, I have a little boy who’s 4 and I’m TTC my second baby!! 👶🏻
My son has just had his 8 week jags yesterday and he has not slept all night, he's been crying all the time, i've gave him calpol, and he has only took one ounce of his last feed? Any advice, he's so whingy and i'm exhausted from being awake all night😫
