I had ds by c-section at 8am, we also told family that visiting hours didn't start until mid afternoon so we could have the day together as a new family. The first afternoon/evening it was immediate family only.

Day 2 was crazy busy with visitors, the midwives picked up on the fact I wasn't handling it and offered me a sign for the door letting people know that visits were to be kept to 10mins by request of the ob!!! Worked a treat! If it was someone I was very happy to hang out with for ages we just told them to ignore the sign on the door! Kept the pesky Great Aunts from staying all bloody afternoon! The midwives actually had the signs made up and laminated so they obviously experience this problem a lot! I wouldn't stress too much about it, be guided day by day how you're feeling and go the sign on the door if/when you've had enough!!!
