Is she paying rent? The obvious problem is that your daughter does not know how to handle money and she looks to you to catch her when she falls. If she is working it is time for you to teach her a solid method of dealing with her finances. Also, she should be paying you rent as well as saving for her own place. Having the children in tow it will be more difficult for her to move out. Make having to move out a part of her schedule. If she refuses to learn these new skills and refuses to pay rent then absolutely look at removing her from your home.
