Partner with you?

Hi, can anyone who’s had a surgical tfmr at a bpas clinic tell me their experience with them letting your partner be with you until you go to theatre or not. I have been referred to a Birmingham clinic as our baby has mosaic Edwards and mosaic turners with no normal cell line. I completely understand you have to be taken to theatre alone but would very much like him with me up until that point. This is so much to deal with and the thought of waiting for hours alone before hand is just too much. Thank you x
