Helaegon and twins dragonrider headcanons because we were robbed
When the twins were born Aegon and Helaena also introduced them to their dragons! After presenting the newborns to the King, they also bring them to their dragons so that they know them and for the baby Targaryens to get used to their presence early on.
Sunfyre LOVES Helaena. Other than Aegon, Sunfyre will only allow her and their kids to ride him. She doesn’t get to do it but Sunfyre loves pets and likes Helaena around. Sunfyre makes puppy eyes at her and it kind of annoys Aegon.
Whenever Helaena is disappointed at Aegon, Dreamfyre snaps at him too ;)
Dreamfyre is protective of Helaena but got even more protective during her pregnancy and when the children arrived.
The twins have time with Morghul and Shrykos. If the twins are good at their lessons they will get to play with their dragons while being watched over by Aegon or Helaena. As future dragon riders their parents teach them how to train their dragons and Valyrian commands. The two young dragons are more than happy to meet and play with them.
Edit: I've read that Maelor's dragon egg is pale green with silver streaks. That would've made a pretty dragon!
