thanks for the reassurance. I've been practicing for temperature trying to get it down to a science and it's not as easy as I thought... the toe warmers I am using (tucked in the third pair of tidey wideys) get very hot and the temp is rising to 102-103 after only about 45 minutes... if I get rid of the toe warmers then the temp is dropping from 100 to 96 in about the same time frame .... better to be warm than cool I know ... I think i am going to add a towel layer over the 4oz shampoo bottle to deflect heat.
