Leaving a DV situation before all of the necessary safety provisions are in place can be incredibly dangerous and put the child and mother at more serious risk than staying for the short term . It's not as we would wish it to be, but that is the truth of the situation for many.

I don't know if that's the case for OP but I suspect it is, since she had already begun the leaving process and it is obviously taking some careful planning. I would rather they got out well, to a place of safety than got out quickly only to come to greater harm.
