just a idea, you could make it 100% clear that if anyone wants to visit bub in the first few weeks to do it while your in hospital, because once your home it will be a "NO ACCESS ZONE" i did this with my family with ds2 and dd. at hospital you dont have to worry about them haning arround all day or being noisy, they have to do as there told and leave once the hours are up, and just let them know once your home you want to spend that time worrying about your baby and sorting out routine and getting your rest, you will let them know when your ready for home visitors.
i told my cousion this when i had dd, that i just wanted to have our family time and get all settled in for a few weeks, she purt the word out to the family and dd was i think a month old when my grandma finaly called and asked if i was up to visitors yet, as i never got back to my cousion!!! (i didnt need to do this as much with ds2 as we were in pascoe vale, to far for them all to travel!!) i wasnt in hospital with dd longer then 2 nights so no-one realy got a chance to see her till easter! (she was born early feb, gosh im mean!!) but by then she was a little bigger and more into lying down and taking in the world instead of eat, sleep & poo kwim?
