HerRoyal I'm sure you don't need me to tell you this, but put your foot down if you need to and insist you are not going anywhere. Engage your inner momma bear.
Ward doc tried to send me home eve of my surgery but I knew my consultant had said 2 nights in hospital so I said I'm not going anywhere unless my consultant says I'm ok to go home. Their response was 'she should have written it in your notes' bah. They spoke with her and relented.
I fear they are saying 24 as that is when baby becomes 'viable' such a horrible word and idea. It doesn't bear thinking about. If you or your husband are up to it, and it comes to it, call them out on that, maybe they will see sense or develop a little compassion.
Oh my goodness I am hopping mad on your behalf.
I am sending you love and serenity, stay put little Royal
