Hi I have two adopted DCs , both adopted at 10 months old. ( now 5 and 2)
We found the process fine if a bit frustrating at times. After applying in the March we had an initial assessment in April and were lucky to be invited to attend pre adoption workshops in the June.
It was December before we were allocated our ( brilliant)SW and February before she started our home study ( form f).
We were approved as adopters at the end of May ( just over a year after we started the process) and were matched with our DS within weeks ( we were very very lucky!)
We brought him home in September and legally adopted him in December.
Hope that gives you a rough idea of how it all works but bear in mind that our timescales were very fast compared to the other adopters in our workshop group.
Having been through the ups and downs of IVF we found the adoption process far less stressful and felt more in control.
Your SW will possibly challenge you and you may feel at times that they are trying to put you off the whole idea!
My advice is first and foremost to be true to yourselves. Decide what age and how many children you think you can cope with and have a good think about the types of issues these children can have - eg drug dependant ( we said yes) , foetal alacohol syndrome ( we said no).The level and type of contact with Birth family is another consideration.
These are some of the tough decisions you will be making but you will be given lots on info to help you make them - and the SW will not judge you for saying no to things you feel you should be saying yes to.
Finally be patient ( very!) and as Kristina say's try not to let it take over your lives - it will help the sometimes frustrating procedure go a little more quickly if you try to focus on other things.
Adoption is wonderful - well it was for me and my family anyway. Good Luck!
