Child 1:

Name: Midnight
Gender: Male
Age: 17
Species: Alicorn
Personality: Midnight is a pretty stoic pony. He usually has a blank face, and it's hard to get him to make any other face. Under that, however, he's actually a very emotional pony. Since he's the heir to the throne, he tries to act regal. He does like to let loose around his friends though (as long as they're not in public). Midnight did happen to inherit his mother's anxiety, and he worries a lot lover his responsibilities.

Child 2:

Name: Starshine
Gender: Female
Age: 9
Species: Pegasus
Personality: Starshine is very bubbly and optimistic, though tends to be an annoyance at times. She's pretty proud of her large wings, though they do get in the way at times. Starshine is brave and adventurous, often stating she wants to be just like her dad. She does have a slight fear of being lonely, so will always try to go with somepony as to not be alone.
