Choose the sex of your baby
The book by Hazel Chesterman-Phillips
Atomic, I saw on a post the other day where you said you hadn't read this book (couldn't find which post it was to write this, and didn't have time to reply then). I know you had discarded it because its fundamentally about timing, but I think it's worth a read. It is old now so I don't doubt that parts are out of date but with respect to timing it's all in relation to sperm count.
Basically her suggestion (if you want a girl and already have a few boys) is that the making of boys, particularly a few of them born in a row is an indication of high sperm count. The reason therefore I suppose she uses timing, is so the sperm count is significantly reduced by the time ovulation occurs as most sperm will have died. She doesn't give a standard cut off but rather suggests you start with a cut off of 7 days (it may be longer), give that a try for one or two months then drop a day, try for a month or two, and so on - gradually creeping up to ovulation. This is why when I read posts about failed sways with a three day cut off after three boys or whatever I thought well yeah of course you got another boy your husband has a high sperm count. It made a lot of sense to me. I had assumed this was the same as shettles (I've not read that book) and so didn't understand the timing conflict with 0+12. Perhaps 0+12 works because though no sex of sperm are stronger or faster there are generally only going to be some that make it in time thus giving the effect of reduced sperm count?
Of course if you give any weight to the female environment then both a cut off (at a time prior to the fertile mucus, which arrives for each woman at a different time but would be achieved starting with a cut off of over 7 days) and 0+12 (the point at which fertile mucus changes to the lesser/non fertile mucus) would fit in with that. I must say however what I'd be more reluctant to chance it with 0+12 as I'm rather abundant in the cm dept so would likely fail with that one.
I can't remember what she said about diet and frequency and I didn't read the chapters on making boys as I've already got two of them. :-)
Whilst I don't think you'll agree with all aspects I think it is a good contribution to sex selection, particularly as it was written at a time when no other information was really available and as you've said in another post, the lacking of any substantial scientific research.
It seems she had much success and some fails as well - to be expected. It's definitely not a swaying route the less patient person would choose and the thought of a one off attempt close to ovulation with a much higher chance of pregnancy is definitely more appealing (to me anyway)...
