I had both my dds there (dd1 2 years ago and dd2 in May last year). I wanted MLBU for both. I had a really positive experience with the Rosie and have nothing but good to say about the staff. I would strongly adivse that you can discharge yourself if all is well and just get home, I wanted to do that with dd2 but a combination of a bad tear for me and meconium in the waters for her meant I didn't stick to my guns and insist. If I have another one, I would be happy to discharge if all was well like that.
DD1 - I started in MLBU but waters had been broken over 48 hrs and I was not progressing after 2 days of contractions 5 mins apart so ended having to go upstairs to the DU for induction. However, I had 1-1 care the entire time I was there and I loved my midwife (male).
Even though we ended up with ventouse (one chance to push before they moved on to an emcs) because dd1 was in distress after the induction started, I genuinely feel happy with the birth experience. I was encouraged to stand/find comfy positions, they were really trying to do the kind of epidural that would allow me some movement towards the end (not possible because everything became a bit of a panic in the end but they were very positive about it). They left us together to bond as a family for a couple of hours, with just offers of toast, tea and bf'ing help if required.
DD2 - I wanted the MLBU and when I first rang at 6am they had space, but then when I was ready to go in at 9am they were full. However, what they offered was MLBU treatment iykwim, just based in the DU.
So I had 1-1 care, in my own room, very very good care where I was able to choose what I wanted. I had a deep bath (the pool was busy), was asked what I felt about pain relief and managed (what I wanted) to do the whole thing with only a couple of puffs of gas and air at the end. My mw was with me the whole time except in the bath when I was happy for her to leave me. I was actively encouraged to be up and about or in the bath and to labour in non-lying down positions.
As others have said, Lady Mary Ward is very busy. Everyone else in the ward with me had had a cs so needed a lot of help with lifting/feeding etc. However, if all is well with you and with the baby, you can discharge if you are happy to do that and as I said, I would happily go home and be in the hands of the wonderful community midwives if I have another. I might even consider a home birth but am personally more comfy with being in MLBU/Rosie.
