Hi cumbria81,
You will need a room for the child to sleep in, and you need to be off work for at least six months after the child is placed, but you must bear in mind that, depending on the child, you may have to stay off work for a year or longer, for instance if your child is not emotionally ready for nursery yet. So you need to be financially ok enough to manage that time off work
I know alot of people choose to adopt rather that give birth, they will go into it in the assessment process. They will also go into what sort of child you could be a mum to, including age then. Personally, I think bonding is mostly about the personalities of the parent and child. I certainly bonded easier with my 10 year old than the 1 year old when he came along, mainly because he was grieving hugely wondering where his mum and dad (foster parents) had gone, screaming and rejecting me, and not reciprocating anything for a while, whereas she, being older, understood what was happening, and really wanted to be adopted, and our personalities just gelled like that!
I think the SW's will view you as a little on the young side, the average age is 38, lots and lots of older people, but it shouldn't stop you, there are lots of advantages to being young and energetic etc.
I think you do need to do research, and really think about what you want. Adoption certainly is very hard for a lot of people, because the children are emotionally traumatised by being neglected, sometimes abused, then taken into care, maybe shuffled around a bit, then moved again to you. So they often have emotional difficulties, and are harder (sometimes a lot harder) to parent than the children of your neighbours and friends would be. That said, it's been the best thing i've ever done. Adoption is something you need to go into with some kind of acceptance that life may well not be a bed of roses afterwards, and that your child may be hard to parent, and need lots of extra help from you, and maybe from others. You need to be able to appreciate small successes and not be driven by academic achievement or anything like that
Right i'll stop the essay now, I tend to go on for ages and not realise how much i've written! I suggest teseearch, and look at the requirement of your local LA as to rooms, work etc. And good luck :)
