keep chris with his son

Hi my name is chloe and I am fundraising for my partner. we are expecting a baby boy on the 8/4 and are a young couple in their 20s living away from their families, mine being interstate and his being in the UK leaving us only having one another. last year we unexpectedly fell pregnant with our little boy. we are so excited for him to arrive however due to his arrival we are needing a new visa for his dad as his current one can not have a child on it. We have both been working two jobs to pick up the extra cash for bills and saving however it just does not seem to be enough especially with myself no longer being able to work. We had almost enough savings before our bank had been hacked and 10000 dollars was stolen from us. the bank has said there is nothing they can do so now we are back to square one. Please any help would be greatly appreciated to keep Chris with his son.
