1 Keeping an eye on 1 child is a lot different than watching 2 or 3 or more kids. 2  Pay should reflect this. 3  Your babysitter needs to control a larger group, deal with kids interacting with each other, and be more aware of group dynamics than if she's watching 1 child.
Ranges of normal estrogen levels are measured in parts pg/ml of estradiol. In normal reproductive age women, during the menstrual cycle, estradiol levels range from 50-400 pg/ml. The actual normal level of estrogen varies during different parts of the menstrual cycle. In menopause, the general range may be 10-20 pg/ml.
A significant amount of estrogen is also produced in fatty tissue. Estrogen levels can range from 400-700 in a premenopausal woman at around cycle day 12 of her cycle, to nearly zero after menopause. At age 60 an average unsupplemented woman will have lower estrogen levels than a similarly aged man.
