Ratchet x reader scenarios

He's a sparkling

Optimus and Ratchet were in the lab working on a new serum when I heard a huge explosion. I looked up and saw Optimus walk towards me with a small bundle in his hand. "Optimus?" I asked. "There was an accident and ratchet is now a sparkling. Until I can make a cure, I need you to watch him" he stated. And walked away. I cradled ratchet in my arms. "Hey little medic" I cooed. He wrapped his arms around my neck and buried his face in my hair. "Shy. That's ok. We'll have a nap then" I lay on the couch and put him on my chest. And a blanket over the top of us.

I woke up an hour after my carrier put me to sleep. I had a nightmare and I wanted attention. So I cried. "There there little one. What's wrong?" She whispered. "Hugs" I cried. "Ok" she said. She hugged me close and tightly. I felt better. So much better that I fell asleep again.

I woke up to someone biting my neck. "Ow" I cried. The bitting stopped. "What's wrong little one?" I asked. "Tummy" He said. "Alright" I sighed. "Hey Optimus?" I asked. "I have the cure. He needs to drink it. Here" he said. And handed me a bottle about ratchets baby height. "Ok" I said. "Here we go" I sighed. I fed him carefully. "Here you go Optimus" I stated. He took him away from me and put him in the medical bed where he grew to full size.
