It's taken me a while but i wanted to read through responses.
And for the record, I'd like to say that the tone of your post wasn't offensive to me but rather questioning and honest.
First, I have heard of a few cases of women having sex with teens, (which is NOT ok) I honestly don't think i have ever heard of a women molesting a child under the age of 8. I have heard of lots and lots and lots of cases or men molesting small children even infants.
Second, I think the question of why a male would chose daycare is a legitimate question. I totally agree with the posters who suggested getting to know him and asking . No where did i read that you were questioning elementary school TEACHERS. As you mentioned in your SWH, Daycare requires alot of nurturing behaviors, Elementary teacher, soccor coaches can also be nurturing but that isn't the main focus of their interactions. A daycare worker, dealing with an 18 month old Is totally focused on NURTURING,-- feeding, diapering, physically interacting in a loving manner. Also the field of daycare, is generally lowpaying and is often a transitional field for many many providers (male and female) on their way to another more desired job (more centerbased than home based, but i would bet the majority of males work at a center).
And third, Men are different than women, in general, they are less interested in caring for children that aren't part of their family. So if we all want to convince Sally S that she really doesn't need to worry about something that is different than what her experiences have been, putting her down probably isn't the best way to open her mind. Sharing your personal positive experiences might go alot farther.
As for me, I've worked in Childcare for many years. I am cautious of male daycare workers, and honestly haven't had an experience where i worked with anyone closely enough to lose that cautiousness. Maybe some day i will, and that would be great because it is true that there are too many kids these days that never see a kind nurturing man.
