I am a social worker in adult SS. As others have said, they are trying to protect your child, but don't let the system back you into a corner. Just explain everything and get evidence for everything that happens. Things can spiral out of hand very quickly if they think you are trying to hide anything, or are trying to deceive them. Neither SS nor the hospital can actually prevent you from leaving with your daughter. You still have parental responsibility, and I assume from what you have said, that there is no legal reason to stop you from leaving. The difficulty will be if you do leave, it might give them more cause for suspicion because you aren't being "compliant". The best thing would be to try and negotiate with SS and the hospital to leave, and to get their permission to do so. SS did close at 5, but there will be an emergency duty team who can take calls. Call in, explain the situation (which should all be recorded on the computer anyway) explain plainly and honestly why you want to leave and that you will come back when the hospital can do the scans. Make sure you take the name and department of who you have spoken to, and ask to speak to the duty manager if you want to to make sure it is clear. Also ask for the conversation and agreement to be sent in writing next week so you have it as evidence of the conversation, in case it is an issue and you need to prove what you have done and why. Make sure you keep a written record of all the convos you have had with the doctors/health staff/ss, so you can refer to it later. I know it will be a massive pain to do, but if it all gets a bit stressful it will be difficult to recall things later on and it will be much easier if its written down at the time.
