im no expert and please forgive me for saying this but iv noticed both sides dont seem to admit there is problems and either hide from the problem, dont deal with the problem or get rid of the problem without dealing with any of it which is why your daughter could have ended up the way she did. one minute shes the little princess next minute when things are getting tough they deal with it by sending her back to you for you to deal with on your own which is not only unfair on you as its obviously hard to get someone who hasnt lived with you for a while to stick by your rules and do as you say and the fact she would have felt deserted by her other family. theyve now took on their grandchild but whats going to happen if she goes off the rails as a teenager? i cant give you an answer for what to do but i do feel for you as you are having to try and clean up the mess the other family have maybes made. take care you deserve a stress free life so i hope things get resolved xx
