Rainbow Dash and Daredevil
Just a little background on Daredevil, he was born a she. Rainbow was a little taken aback when she found out but it did not deter her from persuing this aloof and level headed stallion. They had a tad of an issue conceiving their child but with a tiny bit of help from a very supportive Princess Celestia, Rainbow got pregnant. Their son, Thunder Tantrum, is bit of a buzzkill in his mother's eyes. He can be a stickler for the rules and doesn't like to be brash.
Applejack and Rainbuck
After taking over Sweet Apple Acres, The two started cranking out babies. Orchard Blossom is the oldest and likes school and magic more than farming. Twins, Dusty and Bailey are rambunctious and rowdy colts whose favorite thing to do seems to be arguing over who is better at farming and being helpful. AJ and RB don't really know if thats good or bad, since they fight constantly but all chores get done in a timely manner. Itty Bitty Baby Jonagold is just a tiny ball of giggles and cuddles.
Rarity and Fancy Pants
Being important officials and diplomats, FP and Rares are not the most- uh- present parents. Their daughter Recherché has a nanny who watches her 88% of the time.
Fluttershy and Big Macintosh
After the Second Great War, Big Mac was forced to stop working at the farm due to an injury. He moved in with Flutters and helped her start up her clinic (as well as keeping a very sensible garden outside the cottage so quench his farmer thirst). Hazelnut, a young female moose, was left on their doorstep one night as an infant. She's extremely reserved and quiet but she'll come out of her shell eventually.
Pinkie Pie and Cheese Sandwich
Pinkie is married to Cheese, BUT she had an illegitemate son, Granite Harrison Rock, with Pokey Pierce before he abandoned her. She was then saved by Sandy-wich and they had a wedding and made a daughter named Panini. Harrison is pretty calm in comparison to his mum and step-dad, but Panini is a perfect blending of her parents' upbeat disposition and deep down insecurities.
Twilight Sparkle
Night Glimmer is a member of the magically produced first generation of new pony subspecies. She tells folks she's gender fluid but sometimes its hard for ponies to remember so in some instances NG will be referred to as they.

There is also interestingly shaded Princess Cicada who looks all sad n gloomy.
