Room temperature

I'm due end of June. Just in time for the crazy summer heat. It's reccomended that babies sleep in 68-72 degrees with the rule of thumb being how adults feel comfortable. That crazy cold to me. I need a jacket at 72. Our house is currently 76 degrees and hubby has a sweat shirt on. When it gets hotter outside (but not humid) we let the house get into the 80s. It got up to 85 inside the other day. I was a shade hot but I suspect being pregnant made me a little extra hot. My rule has always been to pay attention to the dog. If he looks like he's too hot we turn the a.c. on for him.

What are peoples thoughts about baby? People did survive before climate control.
