Hi. I have taken the n a relatives child in similar circumstances. We were asked to do so by Children’s Services. It is to the child’s advantage if she becomes a looked after child. She will have ongoing financial support up to the age of 25 if still in education. Also, the school will receive a pupil premium and you will also be able to get some money. More importantly for the child she will be able to refuse when, inevitably, the manipulation begins from her parents.
Other posters are absolutely right that your own children may feel put out or neglected, and the child will need her own room. Your family relationships will change, you can’t be so relaxed about bathrooms, nudity, sex, with another nonfamily member in the house. The responsibility is also more onerous around issues like staying out late, alcohol and drug use, relationships. It seems this child has been neglected for some time, and inevitably there will be issues, that may not yet be apparent. Our troubled teen was deeply detached and numb at first, remote and unresponsive, and just wanting to hide in their room, as they thawed, there were some very surprising triggers, the word “fit” for example throws up extreme reactions.
Most people would probably agree that the biggest difficulties are often in dealing with birth parents, we have had insults, threats, begging letters, suicide notes, and attempts, hospitalisation, harassment ,false allegations, and so has the child. We stopped Contact to protect our selves, but found a way for the child’s contact to continue until they told us they didn’t want it..
You may not want to involve the local authority, but I really think they should be told everything and you should insist on their help. You may well find that you need it.
On the plus side, 2 years in , our kid is doing really well, and we know we have made a difference.
