At this stage I'd recommend keeping an open mind. As part of your training and assessment process you should be taught both what questions to ask about a prospective child once you've seen their paperwork. You should also do a tick box exercise around what additional needs you can accept, what you can't and what you need more information on.
We found that some no nos were easy. For example we live in a house so any child that might need help using stairs was out. Our social worker said no to deafness on our behalf because we don't know sign language. We also said no to children with chronic health conditions requiring daily medical such as HIV and diabetes. Finally we said no to children who had experienced sexual abuse because their are certain behaviours commonly associated with it.
Almost everything else was will discuss/need further information on because things like skin issues, father unknown, parental mental health conditions and domestic abuse can all mean different things and each meaning can have different implications for a child.
2 things to bear in mind our that all adopted children have trauma.
One they are very few voluntarily relinquished children these days. On top of the trauma of being separated from birth parents, most will be have additional trauma because of the reasons they have been removed from their parents in the first place.
Two, the paperwork never gives the full story either of what the child has been through or of the child as a person. Our LO has many issues most of which we manage easily. Some are related to her life story and some are age/developmentally appropriate. Beyond that however she is a person in her own right and no piece of paper could ever tell you all about her even when it includes her favourite colour (pink) and her love of board games.
