Only DP.
With my DD i had planned on it only being me and my (ex) DP, esp not medical students. Well, that was the plan. I ended up having a medical student (who was absoluty fab) my mum, my sister, my cousin (shes a MW) AND my (ex) DP's mother!! Never really thought about it at the time with all the pain etc, but NEVER again! My mum and sis had come into the room when i first got induced and just stayed! this time it WILL only be DP and medical staff, i really dont care if i upset everyone else, this is OUR baby and OUR experence.
Why do people think they have the right to be there or get upset if you dont want them to be? - if you want them there you'd ask!
