How about tfa bots and cons in the humans are cute AU react to meeting a human baby for the first time?
-Optimus is struck by how small and defenseless the baby is and feels a sudden surge of protectiveness. He wants to cup it in his servos and shield it from the world. He doesn't, mostly because he's self aware enough to realize that he knows nothing about babies and worries he would accidentally do something wrong and harm it but he does keep a watchful optic out for any potential danger. All while fighting back a goofy smile as he sneaks glances at the baby.
-Ratchet will deny it but a goofy smile appears on his face the moment he's introduced to the baby. He can't help but croon softly at it when it smiles back and waves a chubby fist at him. It's cute, ok? He's not a heartless bastard, despite what some of his team might think.
-Bumblebee tries to act nonchalant and like he doesn't care but the moment the baby smiles at him he lets out the biggest "Awwwwww" and get the biggest grin on his face.
-Bulkhead doesn't hide his love for the baby, immediately starts cooing over it and does that silly baby-voice when he talks to it. "Who's the cutest little button in Detroit? You are, yes you are!"
-Prowl would die for this baby. He'd kill for this baby. He'd fistfight with Lugnut for this baby. Wants to hold it in his arms so bad but he's a respectful bot that will ask permission from the parents first.
