I have a new baby, he is my first born too, only 3 weeks old.
I am finding it overwhelming how many people suddenly want to visit, when we barely see them! Some not even once a year! Why does it seem like some people insist on flocking around newborn babies !
My partner returned to work FT after paternity leave and weekends and evenings are now very important to us, we want to spend time together as WE wish to. I don't want to give up the little time we have as a family so soon, to accommodate visitors that we don't even see very often anyway!
When I'm at home with baby during the day isn't really good either, i barely have time to eat or shower right now, never mind have guests!
I would like to add that both our parents/brothers/sisters (basically those important and close to us) are very welcome and have spent plenty of time with us over the last 3 weeks, they are not the problem.
Im finding myself getting increasingly annoyed with people ringing up wanting to know when they can come, some even wanting to tell me when they intend to visit!! Why cant people bloody wait a few weeks and give us chance to find our feet and enjoy this special time?
I have tried lying about what we are doing to avoid more visitors, and said i would be in touch when things settle down but they still keep coming back wanting to know alternative times, some have just turned up uninvited! I haven't been honest because i don't want to offend people but I'm at my wits end now and dreading this afternoon because i felt pushed into agreeing to my second cousin coming over! 
Any ideas on how to politely get the message across??? I will be happy to see people in time, but just 3 short weeks ago i had a traumatic labour that I'm still recovering from and now just want to enjoy my baby with my partner without having most of our time eaten up!!!!!!
