Hi Leash - Its great that you have so many people who care about you and your bub! But the last thing you will want or need is people putting pressure on you when you are vulnerable. There are ways that they can really help you (like helping to freeze in meals before the birth), but being near during birth or afterwards when you want some private time isn't one of them. Stick to your guns. Just let everyone know how much you appreciate their concern and care but that you and Shell want to have this time together to bond with your little one. You can control how you communicate what you want to them but can't ultimately control their reaction. Once you become a new parent you realise how much other people project their opinions on you. You may as well start putting your foot down now. If they get offended, rest assured there is no way they will be able to resist coming around (once they are allowed) to peek at the new arrival. I am sure they will get over it quickly.
Good luck!!
