Robot Baby Attack in Pokemon Class

was assistant teaching this small class of babies-maybe 5 year olds with another head teacher. We were reading Pokémon manga to them and then was holding these two young babies close together and one flipped out on the other and started doing this head butt smash thing like an actual attack and we knew this was a robot baby attacking a human baby so I had to stop and smash the robot baby. Unfortunately in front of the kids. I had to bash its head it to make it stop by smashing it into the ground. Then it stopped. It was very realistic so it was very sad. The other human baby stopped crying though and a I think was knocked out for a bit. The main teacher walked off in silence to go get cleaning supplies and this was tough for everyone but it seemed like he knew this must be done too. I hoped I didn't get in trouble for that, but still had a traumatic effect on me and the other kids. Everyone was solemn, but did seem like we all understood this had to be done, like we gave the robot a chance to be human and it failed. I asked them if they wanted to read or watch another Pokémon and the oldest kid, with his head down, said sure, maybe we could try something even more upbeat. Woke up.
