Not quite menopause. Throwing blankets off at night, keeping awake. Fatigue and irritation punctuated throughout the day by heat dissipating from every pore, clouding thoughts, reinforcing forgetfulness. Hair falling out so stubbornly fast. Clothes choosing when to fit. Flooding periods coming sporadically, unexpectedly. They call it “the change of life” – but I feel like a different person altogether. What is happening?         

In perimenopause, the physiological landscape is subject to tremendous change with estradiol and progesterone at the heart of the transition. Progesterone levels fall quickly – no ovulation – no corpus luteum – no progesterone. Estradiol, on the other hand, does not give up so easily. Estradiol levels continue to rise and fall – reliable, steady, wave-like – a biological rollercoaster – approaching the halting rhythms of reproductive senescence.

Now, we parents are the ones squishing up our faces and showing huge grimaces of disgust at the latest report that our baby food is contaminated by metals – arsenic, lead, cadmium – none of it monitored or regulated by the FDA.

The non-profit Clean Label Project independently analyzed 500 baby formulas and prepared baby foods (formula, food, pouches, snacks, drinks, cereals) from 60 companies and found the following horrifying information.

It feels like winter is officially looming now that we’ve all turned our clocks back and the days are getting shorter. In the Pacific Northwest, this also brings darkness and rain for many months and for some of us, it brings seasonal affective disorder (SAD).
