Hun, it's completely your decision! The time that you spend with your new bub and family is the MOST important thing- everyone else can wait!

Also, you shouldn't need to justify your reasons. But if you feel that you do, then your e mail is good. The midwifes at your hospital should also back you up 100%. Get them to come in and kick visitors out after 10 minutes or whatever you feel is reasonable.

It's up to YOU what you want to do and who you want to see. And if people do kick up a stink, then they are only thinking of themselves
