It would really depend on the situation, both my own/hubby's, the child that I would think about taking in and their parents.
My parents have taken in another teen. Her mother had passed away when she was little, her dad was a truck driver so hardly around, her aunts were not the best role models... she was having sex, with child, then lost the child. My parents took her in, I treated her like my sister, we all tried to make her feel loved, welcomed and apart of the family. We only wanted the best for her. She loved that BUT also hated all the rules my parents had (like strict bedtime during the school time of 9pm, no dating during the school week, no sleep at the guys house and so on). She could have stolen from us, we are not sure and really do not care. In the end she decided to move to AZ to live with her dad and his new wife, well 6 months she came back and was with child again. This time she gave birth to a health baby girl, was hoomeless and my parents opened up ther home once again BUT of course with rules, she decided to live with a friend. We babysat the baby once for a weekend, and hear myabe once a month from her now. All we hope is that she has learned that people will love her just for who she is not for sex or whatever else. It is all about being there for each other.
While my parents lived overseas I spent many holidays alone, I could not afford to always go home (or they could not afford to fly me home). I was so thankfully that my friend's family would open their houses to me, some had EIGHT kids and barely could afford to feed/cloth own family. When I turned 18 and got a job I helped them out as much as I could for all the time I stayed with them. My parents did not leave me but I did have to learn to find places to go during the time school was closed down. My parents would send some money, but a pastor makes very little so it was not a lot.
If I was in the position to help I would do so. In fact it has come up but the grandparents decided to take the boy in. I personally would do all I can to be a positive role model in that child's life, if I was able to take them in (for whatever length of time) I would do so. If I could only watch the child after school or during the summer I would do so. We are always so worried about yourselves or just our family that we forget about others, I strive to reach out and help maybe it is only $1 or mayb it is $10 or maybe it is taking them in for a few days or months... I do what I can.
