Just like it's hard to convey what being a regular parent is like, it's hard to understand what being a foster parent is like and the people who have discussed the downsides are stating facts. Anyone who is a parent understands that things aren't always rosy because smiling, sweet infants cut teeth, have dirty diapers, and grow up to be rebellious teenagers. Plus, foster parents have the added frustration of state supervision as well as the foster child's resentment because they want to be with their "real" parents, and a million other issues.
My parents have done foster care for almost 17 years. They have had so many foster children (many of them teenaged girls) that I can't remember all of them. Some have stuck out in my memory, though, and I could tell many stories of destructive behavior and rebellion. I think it's an admirable ambition to help others and these kids definitely need help. I don't think I would ever want to do foster care, but I have a DD13 and a DS8 and I am happy to concentrate on them.
My sister (now 32) lived at home when my parents first began foster care and it was a difficult adjustment for her. Maybe that's why she got married and moved out at 18. It's truly difficult on the whole family when the children are being disruptive. This is also true of biological children, but even the foster children who have tried the most to fit in with our family can be distant as well as extra rebellious at times.
I've often wished they had never done foster care, but then we wouldn't have my 13 year old little brother (who they brought home from the NICU at 3 weeks old with the understanding that he would probably only be at their home less than a month!) My parents still talk to many of the girls who stayed with them years ago. Just last month, mom and dad took their truck 30 miles to a nearby town and moved a mattress for one girl (she's getting divorced and moved). Mom also picked another girl up from her halfway house (just out of prison) and took her to a job interview an hour away from our hometown. These girls haven't lived with them for over 10 years and are in their mid to late 20's. I have very nice parents.
My mom says that rates have been reduced due to budget cuts to the point where she has had to curtail their regular activities- eating out, vacations, movies, etc. Paying for an extra person for everything gets expensive. As one small example, they usually get a 1 bedroom unit for their timeshare and my 13 year old brother sleeps on the sleeper sofa. This year, they have a 17 year old girl with them and have reserved a 2 bedroom unit which takes a lot more points. They've only had to get the case worker's permission to go on out of state vacations and they go monthly on weekend visits to mom's family in WV, too.
