And every time they leave the room , go somewhere their s/o can't see them or hands over to someone else their s/o burst into to tears and won't stop wailing unless they are carrying them even then there would still be some tears
Starscream is Frazzled. He’s one of those stressed-out single parents who have so much to do and no time to do it, and the baby is crying, and the phone is ringing off the hook, and oh no the soup is bUBBLING OVER-! He calls for Wheeljack to please figure out a way to get you back to normal. There’s really no one he trusts enough to hand you off to so you’re on his hip for the entire day. You owe him once you’re back to normal!
Jazz figures out he can keep you from crying with his music. He plays the radio for you on the way to the nearest medic. He’s good with kids, so it’s not hard for him to take care of you, but he can’t hide how scared he is that you might be stuck like this. He’s shaky and dotes over you until he finds a cure. When you’re back to adulthood he falls over in relief- and for a nap.
Rung is calm. Taking care of sparklings isn’t hard, and there’s plenty of weird science on this ship to get you back to normal. He takes you to both Brainstorm and Perceptor, then takes you back to his habsuite to give them time to work. While the cure is being made he shows you his ships and plays patty-cake with you until you’re tuckered out. Then he feeds you and puts you down for a nap. Later, after you’ve been cured, he brings up having sparklings with you.
Megatron is a mixture of worried/holy slag/tired of everything. The whole time he’s protective of you and won’t let anyone else hold you. He even keeps you in his lap while Ratchet checks you over. No one messes with him while he’s this on-edge, and a cure is made as quickly as possible. The whole crew sighs in relief when you’re back to normal.
Drift doesn’t know how to take care of sparklings. Why are you crying? Are you hungry? Tired? He can’t even hold you right. Ratchet pretty much has to stay beside him all day because Drift is clueless but doesn’t want to leave you alone. Eventually he kind of enjoys baby you. Your giggles are adorable and look- you’re trying to put your pede in your mouth! How cute! After Brainstorm fixes you up Drift immediately brings up having a family. You tell him you’ll discuss it later- after you both get a shower and a nap.
Swerve has seen this one movie where the exact thing happened and it was awesome- oh. Oh no no no, don’t cry! He panics and runs to the medbay. He is now also crying. Help, his s/o is a baby what does he do?? Until you’re cured he’s doting mother hen- and even afterward he still hovers a bit.
