Yes, you can either have a child (by being pregnant and then delivering) or just making one in the Create-A-Family section (you just can't create a newborn). You start with a newborn (you can't control this sim), then a toddler (you can control where it walks and asking parents to be held or fed), to a child (full controls), to a teenager, to an adult.

Yes they do. They are todlers for 4 sim days, and thats all i know but as they get older there are more days added on. They don't do anything really special, but only teens, adults, and elders can drive.
