Amy ,hon you have to factor in thedampness , night dew, and night air will reduce the babies bodytemperature to well belownormal body temperature ,. resulting inhypothermia , kinda like whenwe dive into a coldlake we getcold after a few minutes . takeparticular notice after a reallyhot day , go out at nightand just sit there and let thenight air settle on you , it startsto cool the surfice of ourskin and then a smallchill sets in , now beingadults and humans we dont tendto notice it as much , butbabies surely will .
