I adopted my sisters son, he wasn’t however voluntarily relinquished and he was at an age where finding a suitable adoptive family would have been fairly easy. Due to this I had to go through the standard adoption route, rather than an in family SGO. At one point he had been matched with a family and had introductions, but they then changed their mind.
I had a boyfriend at the time who I didn’t live with, SS weren’t overly concerned, they interviewed him once, carried out DBS etc and that was it. He didn’t meet my son for about six months, then when he did it was slow introductions as a friend etc. As far as my son was concerned he was no different to any of my other friends who sometimes came round the flat. He rarely came round when my son was at home, it was normally when he was at nursery or on his monthly sleepover with my cousin.
We did split up, but because he was just a friend who occasionally visited it wasn’t a huge deal. If he had been around him more often then it would have needed a more robust period of stopping contact, my son would have been about two and a half.
That was a while ago and I have been seeing someone else for seven months now, my son hasn’t met him. Again I see my boyfriend when my son is either at nursery or school (he just started reception), or on his sleepover at my cousins.
Depending on both the child and the parent relationships are possible.
LAs vary, in our adoption group there was an approved couple who were married, but had only known each other 1.5 years, sometimes approval takes longer than that!!! She does however need to think about the early days, my son started nursery after five months of living with me, so obviously I didn’t see my then boyfriend for five months.
