It depends on your doctor. I was induced with pill vaginally at 1am. I could still have breakfast at 7am. Just plain toast with Milo. I think it also depends on how fast you dilate. If you dilate very quickly and too near delivery then doctor won’t allow food. If you dilate very slowly then you still can eat. I was only 2.5cm by next morning that’s why doctor still allowed simple breakfast. As long as you don’t put epidural you will still be able to walk around (not too sure for shared ward you might need to check). You can bring your own snacks but you need to ask the nurse to ask your doctor for permission if you want to eat/ drink anything including plain water.
Mine was TMC, I wasn’t allowed to eat anything after they insert the pills. I was starvinggggggg omg, thank god my process only took 6 hours. But due to the side effects of epidural, I only ate like a few more hours later after birth.
I supposed you can still walk around in the ward. only if you're in the labour suit, you have to lie on bed as they will strap you on the monitor.
