I love my Kuya's kids so much that I feel my heart so wide open with concern for their safety and wellbeing. It's typical of Filipino families to be involved with everyone's lives, but is there a line of meddling I shouldn't cross?

For as long as you respect the house rules of your kuya, I think he will appreciate very much having a sibling who loves his kids as much as he does. And his children, esp when they grow older, would love having a second mom in their lives. When I was growing up, my four sisters and I also had our aunt living with us. She was a big help to my parents as she assisted them in taking care of the five of us in sickness and in health, sadness and happiness. Until she had her own family. Now we're all grown up, and have our own family, we still consider her our second mom. and that will never change.
