Thanks for all the great advice

We have a bedtime routine. All of our little ones are in bed by 7/7:30 we do a bath,teeth,read books then bed. Every night same thing. We do not think they are night terrors. We can talk to her and she responds back plus it goes on for hours. Being overtired, crying, we are unable to understand what she is saying due to crying and talking at the same time. It has been just awful.
BUT
She always says she feels hot. Even when it is below zero she will say she is hot. Last night she said she was hot and couldn't sleep. She has her fan on high blowing right on her and the window cracked open but we gave her a cold wet towel and she fell asleep and slept all night.
Same thing tonight she asked for the wet towel and fell right asleep within minutes.
Any ideas for ways to help her feel less hot or more comfortable? We have tried almost everything we can think of !
