Should I be concerned?!?!?!?!

Heather

(Not sure where to post) Ever since I can remember my 2 year old would sweat really bad everytime she slept. Since just about the day she was born she would sweat. I brought it up to her pediatrician and he didn't really seem too concerned. He did tell me she had a heart murmer but it's common in young kids and she would grow out of it. He also said thst he would monitor it over the course of a few appointments. My question is, is this sweating normal? Does it have anything to do with her heart murmur? Should I get a second opinion? She will be 3 in May. I'm silently freaking out. I have pictures but it doesn't do it justice. She's dripping sweat in the middle of the night.
