Oh my! How scary. I will be thinking of you all. Hopefully they have put him in the coma to give his little body and lungs a rest while they let the machines breathe for him. They know what they are doing and probably don't want him to waste energy fighting against the machines.
Dd2 was on cpap/ventilator and all sorts of machines when she was born. I understand how scary it is to see them in that state. Hugs xoxo
