honestly this is controversial but for me sirius with a cry baby reader is always like “what’s the matter baby” “no come give me a hug” like he shelters you 100% anytime you’re crying he’s there to help like he just needs to feel wanted and needed by you i think

like he thinks it’s so pure and sweet when you cry he just wants to shelter that innocence

however when ur crying in the bedroom? then the sympathetic nature becomes mocking

YES!!! THIS IS THE EXACT VIBE I GET FROM HIM TOO!!! the only time he really teases you for your tears are if it's in the bedroom or he'd be holding back a smirk as you cry about a crappy ending for your favourite characters in a book or movie!! but in general, sirius sees tears and he does the opposite of what he got!! he coddles like crazy because he knows from the many times james has gotten him in a cuddle that it really does help!
