Please see previous post "Lactation Data orgy" for background.
It's not looking good for the herbs... or the chump who paid $25 for them.
Between 3/14 and 3/25 over 18 pumping sessions, I averaged 21.13 (+/- 6.9 SD) mL breast milk per hour, 20 minute pumping sessions.
I began taking More Milk Plus 4 times a day Sat 3/26. In addition, I have been drinking Mother's Milk Tea according to the directions. Over 5 pumping sessions including 2 today (3/30), I have averaged 23.8 (+/- 3.8 SD) mL/hr.
A two-tailed t-test assuming unequal variances shows a p value of <0.28.
NO DIFFERENCE
But I continue gathering data and get a bigger sample size... I guess it could be possible that it takes more than 5 days to work.
Even if milk production improves slightly it will still be not enough to feed my baby without supplementation unless is nearly doubles.

Lactation Data Orgy
I really should be grading, but there is data to be graphed!
I use an electric breast milk pump to express milk for my baby while I am at work. I measure the amount of milk produced by each breast at each pumping, along with the time of day and time elapsed since I pumped or nursed last. The following graphs include total breast milk produced, and are posted for fun and for your critique/ interpretation. I am trying to find a pattern in order to further optimize my breast milk production, as I produce only about 1/3 to 1/2 of the milk my baby needs in a day.
Fig. 1
These are the results from two weeks of pumping, with an average of two pumping session per day. These data include both variable times between pumping sessions and variable pumping lengths. I wondered if there was a correlation between how long I pumped as to how much milk was expressed, hence
Fig. 2
It appears that pumping time is correlated with milk production. I then sought to keep pumping times constant at 20 minutes, for the next two weeks and explore whether milk production depended on time since last expression.
Fig. 3
Pumping was complete (as measured by no further increases in volume in last minute of pumping) nearly every session. More informative might be whether the rate of milk production varied with time between expression.
Fig. 4
The data are suggestive of a slight negative correlation, but the non-significance of a linear fit suggests that pumping rate is constant over varying expression intervals. Using this rate as a baseline, I intend to begin supplementing with More Milk Plus capsules and Mothers' Milk tea, two herbal remedies whose effectiveness has not been clearly documented in scientific studies (that I am aware of) to improve lactation. Nonetheless, these remedies are being recommended among laywomen as potent galactogogues. Results and comparison are expected to be posted on this blog in 2-4 weeks.

Stop Naggin' Us
I have a good friend who, whenever we have time for a real in-depth talks, asks me when we are going to solve the distance-marriage problem. Nothing changes in the job situation between our talks, but that doesn't prevent her from asking fairly regularly. She brainstorms ideas of how to get Hub back home, but they are unfortunately the same venues we have already exhausted. I appreciate her concern and even pushing, but it also reminds me that there doesn't seem to be an end in sight. When I have to defend our seemingly endless separation, it makes me feel worse, as if I like it somehow. I certainly don't.

getting cold feet
For the last couple of months, I have noticed my readership go up and my comments go precipitously down ("crunchy moms" post excepted). The blog was originally meant to be a forum, but hasn't been much of one lately. Is there something wrong with my commenting settings, perhaps? Hub is very nervous about privacy issues, especially when I express strong opinions about people or organizations. Any input?

Home Schooled Students Observed
I present to you a _summary_ of 4 case studies of students/colleagues/ etc. who were extensively home schooled.
This is in no way scientific. There are probably many people I teach or know that were home schooled that have not self-identified. In addition, there's no way I can be blinded to the educational status of the people outlined here. Therefore the following observations are purely anecdotal and should not be taken by anyone to support any position you may have.
Of the four people I am referencing, all are above average in school performance. One, my colleague, is rock-star smart, but the three others, my students, were all B students.
Four out of four have loved learning. Two of the students are extremely enthusiastic to learn. They are a joy to have in class, and I predict they will be lifelong learners.
Four out of four are socially uninhibited such that they are noticeably different from their peers. One rides his bike in the hallways of the science building and is slightly eccentric. One is clearly not intimidated in any way by people her superior. She is not frightened to ask speakers or professors questions- really intelligent ones. I'd love my kids to be like her.
Three of the four seem especially close to their families.
I have other observations of home schooling from different contexts: I had cousins who were home schooled and were socially awkward. Very difficult to separate cause from effect in that case. Another observation is from a friend who is home schooling her very strong-willed 6-year old. That arrangement is filled with daily gnashing of teeth for all parties concerned.
I have little interest in home schooling my children because I am out-schooling other people's children. However, if my kids show an exceptional gift that Hub and I are sure won't blossom in the public or private schools around here, I'll drop this job like a hot potato and raise a national spelling bee champion/ enter MIT at 16 / Olympic speed skater.

the REALLY small screen
Before we upgraded, we would Skype Dad every night that he was away at work. This involved finishing dinner and going upstairs to the office where the computer stays and chatting with him.
But I got an iPod Touch recently and we have wireless. So now we have Facetime. Facetime and Skype are pretty comparable in picture quality, reliability, etc. But the big difference is that the little device can join us for dinner, where the computer cannot. So now we call Dad over dinner, and "Dad" sits against the fruitbowl and talks to the kids as if he's actually there.
Boy, 2, has gotten very used to interacting with his Dad on this 4 inch screen. In fact, much giggling is achieved by Boy "feeding" his Dad, in which a piece of food is advanced toward the screen, and Dad makes a big chomping sounds and makes his mouth approach and darken the screen.
Girl, 0.5, will sit and stare at the screen and has just this week begun to smile when her Dad does something silly.
Having the small portable device allows me also to record anything funny the kids do and e-mail it whenever I am in
a wireless zone. Of course other smartphones are capable of this, without the wireless requirement..
It seems strange to watch my children interacting with a small piece of metal, but I think its a great tool to include Dad in our daily life.
