So my family and I took in my brothers other daughter from a previous relationship about three years ago and her bio mom was a real piece of work and the girl lets call her Emma (11) had it really rough and was abused. Now we knew she had behavioral issues when we got here and there are two other kids in the house. Bio moms not in the picture. We have tried everything from loving her unconditionally and giving her plenty of time to adjust and stop and I mean she steals lies and does her best to just cause general disorder she’ll leave the house and not say anything we live in a community with other kids and she will just take off the second we turn our backs she’s no better at school she will cuss at other kids and be incredibly mean to them doesn’t respect the teacher and will mock her she is in constant trouble at school and at home because of how she acts and treats others we’ve talked to her we’ve disciplined her in every way possible and she still keeps stealing her sisters stuff and lying about it we’ve given her everything that they have if not more we’re at our wits end with her and the other two kids want nothing to do with her. What would you do?
