I'm only 7 days PP, but it's been very important to me to have quiet time at home. I had a rough after-birth experience involving a small hemorrhage and retaining part of the amniotic sac, so I was very sore and exhausted aferwards. I couldn't even breastfeed my baby until several hours later. I was lightheaded whenever I tried to sit up, so having visitors wasn't a priority. My DH and my mom were there for the birth, so I obviously didn't mind them being around. Then that night MIL and FIL showed up, which was mostly okay. Then 2 co-workers arrived unnanounced. I was in the bathroom with the nurse at the time, and I looked at her and said, "Oh God, I don't want them here!" and just about burt into tears. They only stayed 10 minutes, though, so it ended up being okay.
The next night my 2 SIL and a niece came. Thank God it was close to 9 pm (visiting hrs end then), so they were forced to leave. I didn't want them there for more than 20 minutes, and I know they'd have never left on their own.
The day after we came home, I felt good and accidentally overscheduled guests. I went in the kitchen and cried because I just wanted to be alone. I asked DH to get his parents to leave, but somehow they stayed another half an hour

For me, 1 guest/group per day is the limit. My mom has been here cooking and cleaning, which has been wonderful, but even she gets on my nerves sometimes. I don't feel any desire to go anywhere (shopping, visiting, etc), but I'm dying to get out for a walk. Hopefully that will happen today.
