The social worker may not be implying that you are not suitable, probably just that you will need to build a bond with the child given you've rarely seen him (I had to leave employment, making us much worse off financially, but giving my and the child quality time together).
The local authority will do anything in their power to place that child with someone who has links with his birth parents, even if it's in a distant way.
My family are going through similar at the moment and to be Frank they are clutching at straws and have asked me numerous times if I would take on my neice (already guardian of another from same mum) but because I've said no as it's not possible, they are asking if I know of any family friends.
So you will stand a good chance if you have no history of a criminal record (particularly anything related to violence or abuse) and your health assessment is passed.
It is a massive responsibility, one i thought i was prepared for given i already have children myself.
The reality is, my friends walked away from me, I am beholden to my mother who in the beginning promised the earth in terms of support but withdrew that support as and when she seen fit.
Stressed? Not coping? Not sleeping? No one to talk to? Ahhhh, she was too busy to help because she had some decorating to do.
My house is desperate to be decorated (infact my home is nothing like it used to be and I'm ashamed) but the times my mother does help is used to catch up with house work/ time with my other children/ sorting through piles of washing and by the time I get turned around I'm ready for bed!
I get very little sleep, very little money for the child and in actual fact this is soon to get completely withdrawn.
I feel let down hugely by family, friends and services who palm me off with leaflets about how to cope with behaviour.
I feel stupid when people say oh well done, you've done a marvelous thing for the child, angelic- like.
When in actual fact I feel a bit bitter deep down due to how much it impacted my life.
On the plus side,
The child is bright as a button, has a loving and caring nature, has an amazing bond with my 2 children (when they are not quarelling) and has become a huge part of our lives.
If you dont have children already I would say go for it, you will have the time to devote to him, if you do have children, think long and hard.
Also make sure you have lots of support in terms of (decent and steadfast loyal friends) or family to lean on.
I rarely get time with my own now, on a one to one basis, and this breaks my heart.
The whole thing is one big rollercoaster of emotions which has left me feeling frazzled, alone and about 20 years older.
