I am searching for dramas with a cute child in it as they are in Autumns concerto, Khun Mae Siam Roy, or ten miles of peach blossom. Is has not necessarily to be an own character. It could be the childversion of someone as well. 

They should be at the age to have their own morals an sometimes even teach the parents how to behave (5-7 years)

thank you :)

  • Natsu no Koi wa Nijiiro ni Kagayaku
  • Papadol!
  • Five Enough
  • KBS Drama Special: I Introduce My Father

Also Hogu's Love and Three Dads One Mom but they are still babies/toddlers.

There are also a lot of daily Korean dramas that start out with the main leads as children so you could look into those as well.

In addition:

  • Child/children of  main leads
    • Wonderful life
    • Thank You
    • Loving Never Forgetting
    • Sunny happiness
    • Only You
    • Jang bori is here
    • My daughter geum sawol
    • Defendant
    • My girl
    • Teriiud behind me
    • laughter of waikiki - baby
  • Sibling or niece/nephew of the MC
    • Dream High
    • Greatest Love
    • My Name Is Kim samsoon
    • Engine
    • Plus nine boys
    • Girls generation 1979
    • Moonlight drawn by clouds
    • My sassy girl
    • Playful kiss - all versions

Additionally:

  • Black | stepbrother of FL.
  • Mother | child adopted/kidnapped/saved by FL. For me, she's actually the female lead of the drama. Certainly steals the show.
  • The Third Charm  | daughter of FL (she gets a minor role during the last part of the drama).
  • Let Me Introduce Her | daughter of the FL and son of the ML.
  • The Greatest Love | FL's nephew.
  • I’m Not a Robot | FL's niece.
  • Children of Nobody | the drama centers about child abuse, so there are several child characters, each with their own unique sense of morality.
