Wanted to do a piece of the Sparkle twins with their momma. No matter how long of a day she had with her royal duties, Twilight was always excited to get back to her babies and fall asleep with them in her arms. She adores her beautiful babies more than anything in Equestria. They adore her just as much (and their dad too, but he works nights) and they always got so excited when they saw their momma come back to them. They practically fought each other to get to Twi first to get those prime snugs.
 
Twilight is also glad that they have the Sparkle family birth mark on their forehead.s (head canon, the Sparkle family all has the mark by their horns like Ursa has.) She was curious about weather or not Firefly would carry on he mark, being born a pegasus, but she was delighted to see that she did indeed.
