I need to be quite vague so I apologise.
Make sure, if you are adopting as a couple, that you are rock solid. Any doubt about your stability as a couple needs addressing before you go into the process.
I have experience (a family member) adopting as a married couple. From initial enquiry to placement was one year. They found out about their now child days after panel, early summer. Introductions were made mid summer. Child was placed with them end of summer.
Child is just a joy, fills my heart more than I can say. Has been through so much in their short life and has no contact with birth parents. Child has development issues and is a year behind where they should be, however this should ease the more secure they feel (so I'm told).
Parent A took to parenting like a duck to water, a bond was formed and it was beautiful to watch the relationship form.
Parent B found it hard. It became apparent, over a few months, that perhaps this parent was not suited to being a parent - wanted to continue an active social life and hobbies, expected child to fall in line with said activities. I had concerns but Parent A said everything was fine, just takes time to adapt.
Cracks began to show, an attempt to save the marriage proved futile and before the adoption was official (8 months after welcoming child into their family) Parent B walked out. There are lots of issues and details about Parent B that I can't say because it would be too obvious to anyone who knows even part of the story.
The upshot of it is, B has not only walked away from the marriage but also the child.
Parent A will now pursue the adoption from afresh, as a single adopter with full social worker support. They were honest and open from the start, accessed all support and basically no matter how high they are told to jump, they jump. Child is number one priority.
I've tried to keep emotion out of my reply as that isn't relevant to your questions (it's hard though so sorry if I've failed!). I wanted you to know that a lot will be asked of your current relationships whilst forming your new relationship.
Parent A is a super star, Child is amazing. Child has massive attachment issues which wasn't helped by B walking out. Child is still young, I'm sure their issues will cause testing times in the future but hopefully our family can rally around Parent A and support, as we always have done, to ensure Child grows up feeling loved and secure.
I wish i could share a picture and proper details, so you could all agree with my OTT proclamation that Child is a true delight! 😂
