Mama, is there no way that could consider pressing on with it now anyway. I only say that because realy, there is no ideal time to welcome a child into the world or to a new family anyway. Its always such an upheaval and most families have pressures and issues rumbling away in the background 24/7.
I don't have experience of adoption Im afraid but when all my children were born, there were always issues in the background - family stuff, relationship stuff, health concerns, financial issues - you name it! I guess that because we didn't have a say on when our children 'arrived', we just had to accept it and muddle on.
Having said that, I have no idea of what is going on for you at the moment but f you heart is aching for another child, shouldn't you just follow your heart. The sooner you do it, the sooner you can all adjust and settle down again.
You said your mum is ill, Im so sorry to hear that. Wouldn't she be delighted though to meet a new grandchild?
Feel really [cross] with SS about wanting to tidy thing up, you can't tidy families away for gods sake!
