Prayers needed!

Just got a call from my husband. Our nephew who turns 1 next month is in a coma for low blood sugar. Haven't been able to figure anything else out cause he's in another town and can't get ahold of our sister. All of her family is here and she went up there with her piece of shit baby daddy. She's only 17 and he's 27!!! I was there her whole pregnancy and first 6 months of his life. I'm trying not to freak out cause I know stress is bad for me and my baby but that's my little mans. I don't even know how to feel. He's to young for this. Please say a prayer for him and if anybody's been thru anything like this please tell me how it turned out! Thank you in advance
