Transformers Prime: Sparklings

I've read a lot of TF fan fiction involving these cute little guys. But I'm not officially sure if these Sparklings are cannon to any other Transformers shows and comics other then being shown in the third movie and the TF movie comics.

The TF movie comic shown these little guys in various pages, but they were called Hatchlings instead of Sparklings. I wonder if Cybertronian can breed through spark merging or similar of how humans do it?

This what I think they would look like if they made a appearance in Transformers Prime.

Here is Mech sparkling who is a Seekerling, and a Femme Sparkling that is a grounder. Also I decided to draw other Sparklings to get a good idea of how they came to be. Yeah, I decided to go by gender even though some people are going to argue against that.
