Hidden in Statistics

Since I've had children, I have repeatedly heard mothers demonized for letting their baby sleep in bed with mom. After a few months of insanity with child #1, I seriously thought I was coming down the post partum depression. The shrink said, "you're not depressed, you're sleep deprived."
I let my baby sleep with me. Nurse him every 2 hours by getting out of bed? When he would sometimes nurse for half an hour? Are you kidding me? No. Let Jr. sleep next to me: he nursed, I slept. This is not something which requires me to be awake. Of course, I'll probably be demonized for not looking adoringly on as my baby validated my womanhood and bonding with my child.
So - what do the statistics actually tell us?
Study says: Increased risk of crib death by 50%.
Oh, my god, get the baby out of the bed!!
But ... What are those risk factors?
Drinking and taking sedating drugs.
What if we only look at mothers who don't have those risk factors?
Wow - there is no increased risk of crib death.

PTFE Exposure

PTFE (polytetrafluoroethylene) is Teflon(TM), which people will tell you causes cancer or whatever. It might. If you ever get exposed to it. The science is absolutely clear: Teflon-coated pans are safe up to about 780F, a temperature at which anything in the pan will have caught fire. So, as a rule of thumb, you should be careful when flames start shooting out of your nonstick pan. Soon it might get hot enough to emit toxic Teflon particles. People scream about "Risk!" without comprehending what it really means, even qualitatively. Risk = exposure * hazard. therefore .... No exposure = no risk. No doubt this is one of the most difficult problems to overcome, psychologically. Even if the worker intellectually knows this ... their definition of "no exposure" is rarely the same as mine. Well, I suppose "no exposure" is the same. It's the "acceptable exposure" whichis the sticking point ... unfortunately, Teflon doesn't help with this no-stick problem. .

HSE chair Judith Hackitt said children needed to learn how to manage risk. [HSE = Health & Safety Executive - the English sort-of cognate to OSHA] Wow - what a concept! Nearly half of teachers believe the health and safety culture in schools is damaging children's learning and development, a survey suggests. When questioned by Teachers TV, teachers complained about a five-page briefing on using glue sticks and being told to wear goggles to put up posters. I am curious about whether the 'five page briefing' was actually an MSDS...

Phthalates - EPA assessment?

Oy! yet again, one is confronted with material from academic courses, and realizes 'hey, this actually was useful!" EPA considering risk assessment for phthalates

Phthalates have been used in toys, cosmetics, personal-care products, food packaging, pharmaceuticals, medical devices, and cleaning and building materials. They have been found in products such as teethers and pacifiers that babies put in their mouths.

President George W. Bush signed a law this year banning three types of phthalates in children's toys and child care items, except for minute amounts, while temporarily banning three others pending further study. - well, even an idiot can get it right once in a while -

The same six phthalates have been banned in European toys for nearly a decade.
