OP, 
Really, really hope you've phoned the police/ Women's Aid, and got yourself and your baby girl SOMEWHERE SAFE by now?
They will do the thinking and organising for you, after 1 phone call.
You can do it, even though it feels so hard right now.
Please let someone else help ease your strain.
(Even if that means rushing round to a neighbour's.
.
If you're worried about putting anyone out, or not knowing them well enough to arrive on their doorstep, wait by their door whilst they ring the police on your behalf.
I'm being totally honest by saying that, if a vulnerable mother and child turned up at mine in such a situation, I'd be only too willing to help).
Your mind must be in such turmoil...no need to plan anything else at all right now, or concern yourself with the bigger picture, just focus on doing that single thing for now.
After that one phone call, others can and will support you and your little one.
By prioritising your DD's welfare and safety, you will be acting in her best interests.
This will count hugely in your favour re child protection (contrary to his lies you've been threatened with).
Wishing you strength xx
