Congested baby 🥺😷

For the past 2 days my baby has been very congested. I can hear a lot of snot in his nose, but when i suction it i can't get everything. I think he's also having trouble breathing... when he breathes it sounds like he's snoring. He also has been coughing/choking a little on mucus from his nose. He seems so miserable and i hate seeing him like this. He also hasn't been eating as much as he used to.. when i make his bottles sometimes he'll eat it all or just half of it. Any suggestions on what i should do to help him? He has his 2 month appt Friday so i will mention it to his dr.
