I am going through this at the moment. Not me obviously but our nieces and nephew may be coming into our care. I can not speak for other states but i can for WA and i can say now that i really want to slap anyone who said that their child was removed for no reason ect. There is A LOT involved in removing a child from the care of their parents. I am seeing it first hand. My nephew was only 2 weeks old and close to starvation, they have had multiple reports form family, friends, complete strangers and health professionals. there are also violence reports and the police have rang DCP and asked why on earth these kids are still in their mothers care. But DCP maintain as much as they want to take the children they cant cause there is not enough evidence that they can use in court.
Any way long story but i guess what im trying to say id that i would bet money that there is more to the story than you have been told.
I really hope that they are able to sort them self out so their child can have a happy, stable , safe family life!
