snoring kids

Hey. I am curious as to how to stop snoring in my 3 year old daughter. She don't have asthma or anything. But since she was born, she snores! And it's very very loud. It over throws my husband. Now I can take light snoring. But now cuz I just had my son and he do not snore.. it shakes him up and wakes him up out of his sleep! 😓😭 therefore the crying and I have to get him back to sleep. Very frustrating. My son can take light noises but if you can hear my daughter in another room so loud, you would thtibknits a grisly bear. Is there anything to help calm down the snoring and make it sound lighter or maybe even stop? It would be a big help. 
Sleepless mommy!
