Father Figure

Staying in DS house making me more and more realize how Megan miss her daddy and craving for a father figure.
Whenever SF called his daddy 'pa pa', she'll looked at her yie-chang with yearning eyes.
Whenever BIL was teaching or playing with SF, she'll go to them and joined them. She tried her best , the best as 2 years old baby could, to catch the attention of BIL. She smiled a lot to him, followed him everywhere he went and do what ever he told him to do, no a single word 'mai' came out from her mouth ( which is her favorite word whenever we, ds and i or even kong-kong and phor phor ordered her to do something)
When BI taught her number puzzle, she listened tentatively and mastered them immediately .
DS also noticed and this really break my heart.
Well, I realized that she's the victim of the situation, and this make me felt guilty and soft when ever she demand something.
I know i shouldn't pampered her but sometimes seeing her angelic face, i just could not resisted and just heading her demand.

What should i do......
