for verbal abuse ... yes. For ignoring them when they need their momma.. yes. but for messy homes, no.. I know several people who grew up in a messy homes and it didn't bother them at all. My friend is one of them. Her mother still gave her the attention she needed when she wanted it. Sure she would have gotten sick but guess what, her mother even took her to the doctors. but she was lazy about cleaning the house. Every heard of "Clean House" on tv... well those type of situations IS real, I've seen it lots of times.
That's why 22 years for dirty home is very bad for the kids. What the parent and kids really need is for the social worker pull the kids out until they got their house straightened out in a proper condition for the number of kids they have, and then to check on them often, But if the kids had to deal with other type of abuses, I think the kids would be very happy to get out of that situation.
