DS is 11 weeks old. He started daycare at 8 weeks and came down with a cold. He fought that off but has stayed congested, then my DH and I got it way worse. Now he has it again and it is accompanied by a cough. The coughing is keeping him up at night and scaring him. In the morning he is throwing up so I think his stomach is full of nasal drip. Our doctor was out yesterday so I took him to see another doctor that dismissed it as a prolonged cold. I googled and now I'm worried.

Is there anything I can do to help him be more comfortable? We are doing sinus washes, sitting in steaming shower, bed is elevated. I'm at a loss and no one is sleeping right now.

ETA: when we went in for our two month well check our doctor mentioned putting him on antibiotics just incase but they made him REALLY sick. I need an antibiotic to get over it myself.
