belindarose Please don't cry! Your post really rang bells for me, I am 37 weeks through my 3rd pregnancy and have managed to stay calm and cheerful throughout, until the subject of visiting came up recently. Since then I have been crying myself to sleep about it regularly, so you're not the only one.
It is SO hard to manage visitors' expectations and it does make me cross that people are unable to put their (understandable) excitement to one side if the new family need a bit of space.
Previous experiences have taught me a few things...
Firstly, it is of paramount importance that you put yourself and the baby first for the first few days, and try not to feel responsible for managing everybody else's wishes.
Secondly, people can put a lot of pressure on you about visiting, but those discussions are often forgotten once they have actually seen the baby.
Finally, plans are often redundant, because no-one actually knows what circumstances you will find yourself in until after the birth, let alone when the baby will actually arrive. You yourself might be desperate to show your baby off on day 3 - then again, you might need more time to recover. It can't really be planned with precision, and the people who really care about you will appreciate that.
For my first birth I went along with the whole family's wishes and tried to book people in fairly for equal visits, in order of closeness to the baby, etc. Despite this, people largely did what they wanted. Me and DH were too tired and bamboozled to manage it all. I completely wore myself out by day 5 and ended up having very little left for my baby.
On the other hand, my best friend's Mum sent me an email shortly before BF had her first baby saying she would not be visiting until the baby was a week old, and that although this was going to be really hard for her, she wanted the best start for her grandchild and daughter. So people ARE capable of putting the new family first. In the event, BF wanted her Mum there much earlier so she was delighted to be invited round on about day 4.
Please take care of yourself and try not to let this spoil the last days of your pregnancy (must try to take my own advice!) Good luck!
