constant monitoring is a pain. Ask if they have a portable unit so that you won't be tied near the bed, but if they don't then you can still move around the bed, on the ball, on all fours, etc. It is easier for the OB and midwives if you are on your back on the bed because the belts are less likely to lose contact, but that is their issue not yours and if you need to move around then so be it, it will make your contractions easier to cope with.
