When i had both mine id didn't have family around and with #1 i was being induced and #2 elective c/s anyway so my friends did know the time etc but they wouldn't have dreamed to turn up to the hossy until i texted them ok. I really wouldn't tell anyone other than those people you actually want with you when you give birth so that you can decide after the birth when to tell other people and let them show up. You might feel like visitor's straight away but then you might not and i don't think you'll know until the day! I would be annoyed by your friend' comment too as it should be yours and your only as to who you want around. Good luck
