Hi op
I'm a nurse. I work on neonatal so work with maternity a lot.
I can tell you what happens with us/our maternity with someone in your situation if that would help,
In baby's medical notes a social risk plan would be inserted.
On the plan will state why you have a social worker
We document when you visit and how you interact. We are not there to judge you we are there to support
(Not saying your baby will need to be on neonatal but same goes for maternity with us)
There will also be contact details for us to inform social services that baby has been born.
It's very very rare babies don't go home with mum. There is lots of processes, parenting assessment (which they can't do until baby is born) housing assessment (to make sure your housing is suitable)
And as you're working with pediments health midwife she will continue to follow you up afterwards.
You sound as though you have a good support network with your mum, and your ex. So if you were to be unwell they will hopefully be reassured that your mum would be perfectly capable of helping to take care of baby until you're back on your feet.
Social services can't tell you a plan right now because they don't know what will happen after the birth. It's better for you and social worker to build a good relationship before baby is born and this will help the process afterwards
It's important you continue to attend all appts and meetings both with your care and social services,
It might help to write things down before meetings if you feel there is anything you want to ask/say,
Take your mum with you, this won't be seen as a negative bias thing, she's your support, she will be involved when baby is born so they need to get to know each other too (your mum and social worker)
Good luck op!
