This graph shows only babies born as a result of spontaneous (non-induced) labor (76% of all participants).
Do babies come on their due dates? Not really. But they seem to come around their due dates. In the survey, only 477 out of 10990 (4.3%) spontaneously arrived on the exact day. But if you look around that date, the numbers get bigger fast... 2722 babies (24.8%) arrived spontaneously between 39 weeks 4 days and 40 weeks 3 days. 5146 (46.8%) arrived spontaneously within a week of their due date. Throwing out inductions makes those percentages even higher: 61.5% of all non-induced babies arrived within a week of their due date.
I also think this graph is important because it shows how meaningless it is to move a due date one or two days. For example I have a chart comparing first time moms to mothers who've had previous births, and it shows about a 1-2 day difference. But based on this graph, who cares about a day?
What I mean is this: a woman who's not induced has a 61.5% chance of giving birth within a week of her due date. Let's say we lie to her and tell her a date that's three days early. Now she has a 60.4% chance of delivering within a week of that "wrong" date. It's not really a huge difference.

If you are is the USA, then Babywearing International (
If you do decide to go for one of the more expensive ones, you can get some good deals on used carriers that are still in great condition. I have seen a lot of Ergo carriers for sale on Craigslist and if you use Facebook there are some sales groups too - search for Babywearing On a Budget, which serves North America.
eh go ahead and eat them. I recommend ketchup, though. Or hot sauce.
Oh and congratulations and all that, it'll be fine. People do get weird but here are some random responses:
"well, I guess we were wrong!" cheerfully
"Shit, we we were wrong. OH well.
"IDK do you think we should get rid of one of the others?"
"You want one?"
"Well we weren't sure the first three would be enough sustenance when the apocalypse comes"
"We have W girls and Z boys, we're hoping for something in between"
"Actually we're hoping it's a cat"
"Did you realize that we just sent a new spacecraft to Jupiter? Isn't that exciting!"
Sorry, if I was not able to mention other details. Actually, I have a (US) medicare insurance. And I am particularly referring to this denial management software which help clients with their claims. Thanks for your reply.
For the first two birthdays, we tried to make some special food and splurge on interesting fruit. If I lived closer to friends, I would want to throw a get-together as an excuse to see my friends, celebrate our survival of another year. I don't think my kid would actually be into that though. They are turning out to be quite introverted and shy.
I wonder what other primates do and if it varies much from family to family or within family.
Do other primates have screaming babies?
I took a few physical anthropology courses in school (Mostly classes on primates) and I now have an infant. It's amazing how often I think "Oh man, that's exactly how a baby capuchin monkey would act!" when he freaks out. Mostly baby primates just freak out when separated from their mother, their mothers deal with this by letting their young be attached to them pretty much 24/7
It's true though. You don't get a good night's sleep until they're an adult. Looking back, I don't think my mom slept a wink my baby brother was born lol
I do find it very interesting to find that IKEA is recalling furniture because people don't secure it to walls... I was given anchors with all of the stuff I've bought from there. Though maybe that's only a somewhat recent thing? It was over a half a year ago that I bought stuff from there, though.
And I didn't use the anchors... I guess I am about to be an aunt and it might be a good idea to get that stuff secured in case I ever end up watching my niece here. Hadn't really worried about it prior because there was literally never going to be a time I'd have kids running around this place. The likelihood of my niece ever being here is pretty damn low too, but I wouldn't say 0%.
One of my friends is part of this magazine. She didn't write this one but it's pretty hilarious.

Anyone want to come up with our own "Guidebook" titles?
I don't think it's a cause for immediate concern, but my experience would lead me to talk to a doctor about it. I didn't have a stutter when I was 2. I had language delay. I didn't learn language when kids typically do. Needless to say, I was a very frustrated little kid. When my parents and my pediatrician caught on to it, I had to spend a few years seeing a speech pathologist.
I've read that stuttering is at least partly psychological, but I really can't say more than that. If nothing else, I'd just want to know that his frustration is a necessary part of development like teething and not something that can be avoided.
All I can think of is the Arrested Development episode where George Bluth Sr. has a hot tub installed in his attic hiding place so that he can boil food in the bag.
I've not boiledfood in a bag, but not due to any aversion.
oh, lord, i am so tired of people telling me to "enjoy it!" regarding my newborn. and asking me if she is a "good baby." how could a baby be bad? and how does it make me enjoy her more to be reminded to do so? i imagine that if i was depressed and had a colicky baby these questions would be even more obnoxious.
Don't be silly monk, everyone knows a good conglomerate goes better with milk
I think it depends on the child. Do you ask a newborn if it needs it's diaper changed? Obviously no. Do you help a 13 year old get dressed? Obviously no. Somewhere in there the child matures to the point where they should learn that they own their bodies even if they don't have all the privileges an adult does. This age is going to vary wildly between different children (by widly, I would say 3 year range). I would guess that some kids might be ready for this lesson as early as 3 while others not until they're about to go school. Actually that's a pretty good benchmark, because if you're going to put them in a group with other kids they don't know they should know the rules about touching or being touched.
As far as kissing Grandma, maybe they shouldn't have to do it, but making them do this social communcation helps get them ready for all the other social communication that will be forced on them later. Plus, grandma needs that love to help HER be healthy.
