FWIW - I had reservations about my mom being there, but I invited people over anway - my mom and dad, dh's mom and dad, and my sister. I didn't want anyone with me when I was in labor, but when I started pushing I didn't mind and had my mom, dh's mom and my sister in the room. My mom didn't really bother me at that point.
That being said, I didn't have them back for the next birth!! I only had people there with "jobs". No one's job was simply "to watch". To each her own of course, but I felt so watched because that was all they were there for the first time. They left my spotless house a mess with their cups and snacks it was ridiculous. I still can't even believe they would leave our house messy when they walked into it spotless. My husband was awake just as long as me. And while he wasn't giving birth - he was a first time dad, and had never been through labor and birth with me before, and he was tired!!!
So the next time I had 2 of my best friends come. One to take pictures and use the video camera and the other to take care of my oldest (she was almost 2). It worked out very well. I didn't mind them being around because I knew they had things to do. I had everyone else come over afterward.
Someone asked about how much trash is there. There isn't a TON of trash, maybe one or two garbage bags full. We buy the 30 gallon size as a rule. Usually midwives double-bag, so have plenty available. We usually use a trash bag for laundry too. Towels, sheets, washcloths, baby blankets - that go into the washer (usually the midwife puts them in before she leaves) right after things calm down after the birth. But there is trash, the chux, the gloves, wrappings from the bulb syringe.....there's trash.
The phone ringing never bothers me...be it my cell or regular phone. I don't mind talking to people when I am in labor. Obviously, if it is intense, I don't answer the phone, but it doesn't bother me ringing. Everyone is different. I don't think you need to turn your phones off unless you KNOW it would bother you - you might be surprised at how calm labor makes you. It seems easy to deal with things while you are in that calm state - ready to deal with contractions. I might think people would come knock on the door if we turned our phones off. LOL. I WOULD put up a sign on the front door asking for no knocking or doorbell ringing unless the guest was invited. That will show people that just MIGHT show up randomly that it is not time to visit.
I always want to eat after I have my babies. I think I've always been hungry, and if I wasn't, and had food anyway, I devoured it anyway. Yogurt with fruit, bagels with cream cheese, a hearty bowl of potato soup....something with a little protein and some carbs just HITS the spot after all that work and helps me sleep better (it is so hard to sleep after a new baby comes!!). So have some good snacks in the house (grapes are wonderful during labor) for you and your care givers.
