6 month shots- hurting baby

**UPDATE: thank you all so much!! Baby fell asleep but when he woke up a few hours later crying in pain, I gave him Tylenol. He was back to being his happy, sweet self the next morning. Tired- but happy. Really appreciate it!

My sweet happy boy is having a really hard time with the aftermath of shots. He got them 5 hours ago and he’s crying instead of sleeping. He also got a flu shot and never reacted this way when he got them done at 2 and 4 months. He’s definitely in a lot of pain, I was holding him and slightly adjusted myself, which moved him, and he burst into tears. I can’t let him suffer all night, is it safe to let him have Tylenol? More so in the middle of the night if he’s still having a hard time. Of course id love for him to sleep through what he can but it’s so inhumane to let a baby suffer like this
