Just to echo some of the positive experiences:
The process can be long and sometimes frustrating because of the admin. However, each step of the way, we were kept informed about what was happening and why.
People say the process can be brutal - I think it felt like that at the time, but I don't give it a second thought now.
The training prepares you for possible difficulties. You can withdraw at any time. If you have questions or worries about anything then you can ask them. The pace can be slowed if it needs to be.
We were supported by social services and BAAF every step of the way. No question was ever ignored.
It feels long while you're in it... But so does conception for some people. So can physical pregnancy.
You become a parent way before you adopt - the day you realise it's not about your needs, and is only really about the child's. That's when you're ready.
I have two adopted children. The first was 12 weeks when he got his adoption order and 16 weeks old when he came home. No physical health needs. No additional trauma (unrelated to attachment/removal at birth)
Prior to adopting him, we went through the home visit and training process for around 2.5 years (I think it was 2 years to approval panel from first enquiry)
When he was 18 months old (so had been home with us for around a year) birth mum had another baby. We had been made aware of this around 6 weeks previously. Baby was removed from birth mum around a week after birth, and she came to live with us after 2 weeks in Foster care. The adoption process this time was very straightforward and we adopted our daughter fully, with the adoption order completed before she was a year old.
My DC are 14 and 12 now and we are extremely happy.
They have older siblings who were placed in other families, and we see them regularly, even now the oldest are late teens. My DS and his older brother are especially close and we've even had his brother over for sleepovers.
I have no biological children of my own, so I don't have a direct comparison, but we don't seem to have had any difficulties beyond what most families experience.
I love them fiercely. They are my everything.
They both weirdly look like me (more like me than DH) in that they have the same eye colour and same hair colour. Their mannerisms and affectations they have inherited from us.
They're both quite proud of being adopted and talk to their friends about it sometimes.
It's not true to say there are "no babies" in the system. Through my experiences, I also occasionally sit on an adoption panel (in the role of adopter) and babies are fairly routinely adopted, many without additional health complications.
It IS and can be a difficult process, but that is to prepare parents and to make sure that the fit is the right fit. The social worker has to be confident and be able to vouch for you as a parent, and so they need time to get to know you and be sure.
I was a bit overweight when we adopted and neither DH nor I are big earners. We do have a three bedroomed house, which helped, but it was much more about suitability for a growing family than a blanket "you need a massive house with a garden"
We also have a good support network and we were able to access some decent local services, so that was also useful.
Everyone will have a story or an opinion, but the truth is, the training will both prepare you and will answer any doubts. On our training course, 6 out of the 11 couples dropped out because it started to feel wrong for them. For the rest of us... It just went right.
The best, hands down BEST thing we ever did by a trillion miles.
