About a runaway brother and sister.They somehow end up in a house with a couple that don't have kids. The wife may be sally fields but I'm not sure. Anyway the girl is a trouble maker. I remembe her spraying a hose and she dosen't like her neighbor. I hardly remember it but I have been looking for years. It's not on their own.

Try this:

Help Wanted: Kids (1986) (TV) - Plot Summary

It stars Cindy Williams - who might be mistaken for Sally Fields if you're not too familiar with her - Can you remember if there was a scene that involved a HUGE mess being made in the kitchen by one of the kids, but the brownies (cookies?) were really, really good (I think one of the adults was extremely surprised at their taste?)...
