omg i totally forgot to factor in your worldbuilding forget the second ask. maybe tc takes to holding his blob against his chest bc he can feel their spark pulse against his own. as a result even when kid is an adult they’re always giving warm hugs to tc and jetfire too.
Oh don't worry! While I obviously have a preference for my own worldbuilding, I don't mind reading and talking about different hcs. Like, I like when people get creative, but I also think the classical "baby but robot" is cute!
Now, this is cute! And a hc I have. Kind of like babies with their mother's heartbeat, sparklings find the pulse of the bot who carried them really soothing. The easier way to calm one is to put them agaisnt their originator's chest (though this sometimes doesn't work rip). It's something that often extends to adulthood.
But Thunderfire kiddo would totally be a hugger! I think that both Thundercracker and Jetfire would be really physically affectionate with each other and it's something that would end up rubbing off on the kiddo
Also the image of Thundercracker gently holding their sparkling close to his chest 😭🩵
