As one may expect, the Decepticon family has many differences from those of biologicals. Still, there are many similarities, as well.
Most of the differences start with what biologicals would call "conception," and other differences follow on from that. Since the making of a Decepticon is very different from bio-species right from the start, it must be looked at in order to understand the Decepticon family.
A Decepticon family usually starts with one person, rather than the two or even three of bio-families. This person is the Coder - the one who is responsible for writing his offspring's initial script.
Decepticon Coders will write the base code with an eye towards their offspring being able to thrive in our unique, lawless society. National traits are often entered into the root code, mainly to prevent offspring from getting themselves executed out of ignorance (they will be able to change even their root code once they're fully mature). Also, the Standard Educational Data Pack is preinstalled. If the Coder is wealthy, several Advanced Educational Data Packs may be preinstalled as well.
Finally, it's time to activate the new Decepticon. This part, despite its vast physical differences, has a result similar to a newborn human being born. The Decepticon "baby," though full-sized and full-strength, knows nothing other than what its base code says. The new robot won't even have accessed his Educational Data Pack(s) yet, and he'll basically look around in a dumbfounded way - similar to a human infant, but standing up.
Finally, the robot's eyes will fall onto the other robot in the room: the Coder. Due to its base Code, it will recognize the Coder as its parent and look to him for guidance in this new world.
Since Decepticons don't have to waste years on "book learning" thanks to the pre-installed Educational Data Pack(s), their maturity will progress at a greatly accelerated pace compared to human children.
For the next 4-5 years, the Coder will provide parental guidance, nurturing, and moral lessons - much as a biological parent does. Despite the Decepticons' violence, raiding, and overall shadiness, there are actually several morals and cultural norms to learn in order to get along well in Decepticon society - they just happen to clash with those of some other societies.
The Coder will also pay special attention to developing his offspring's ability to actually THINK! For an offspring to attain true sapience, the Coder must not only program to allow the possibility, he must actively nurture the child's abilities in that aspect. Decepticon Base Code is intentionally written to NOT cover many situations, in an attempt to force offspring to figure things out for themselves. This doesn't apply to "booklearning" itself, but to real-life scenarios and to the actual application of what they've learned from their data packs.
Still, Coders do a lot to encourage their offspring's sapience. It's arguably the most important part of Decepticon parenting. Done improperly, you end up with an expensive fancy machine. Done right, the result is a living robot - a Decepticon - whose metal body is an asset rather than a liability.
