Hey B.,
I am not sure it is Reflux either. Of course each baby can express different symptoms and have varing degrees of severity.
If you think it is just mucous and based on what you describe I would almost agree, then I have only one suggestion.
Most people use saline drops and suctioning wrong!
Not saying you are as I am not there to see.
You are suppose to put a few drops in each nostril.
Wait for them to mix with the mucous.
Then squeeze the bulb syringe in.
Then place in the nostril you are sucking from at the same angle as the nostril flares. Also at the same time place you finger over the other nostril to seal off and release the bulb. Of course release the other nostril too. It is easier said then done, takes practice and is best learned if you have your doctor or nurse show you how to do it. You repeat this multiple times and you will be suprised by the amount of mucous you are able to pull out.
I can tell you that I did not get it right for my oldest until she was near 7 months when the doctor asked me to show how I was doing it. I have it down now for my second and the stuffiness is better after suctioned.
Of course you do not want to over suction as you will just cause inflamation in the nasal cavity, so I think you are only suppose to do it 4 times a day. I do twice a day, in the morning and then before bed when congested.
Though your baby is only 6 weeks and so I highly recommend having your doc show you how to do it.
Only other things in general that have been told to me by medical persons and are now part of my opinion. are:
Babies born before 39 weeks have a higher incidence of reflux.
Spitting up does not mean acid reflux.
Baby bottles should not be thickened with cereal until 4 months.
When adding cereal, start with Oatmeal or Barley, rice ceral increases constipation.
If you think it is an allergy, switch to a soy formula.
As for thickening formula to keep it down for a child that acid reflux, one that spits up alot or one that has congestion and just needs the formula to stay down out of the way of mucous, try a ready to feed mix like in the ready made nursette bottles or in the cans. Powder formula once mixed with water is not the same thickness as ready to feed formula and so it is lighter and comes up more often. I know this for sure and spent alot of time verifying this information.
I am a mom to a severe acid reflux baby that could keep nothing down and no med helped until she was nearly one. To add to that she did not stop vomiting until 2. We still have GERD, and are hoping it is outgrown with age, though not likely. We maintain an acid free or reduced acid diet and have not needed medications for almost one year. And now onto to baby number 2 who is a stuffy allergy filled blessing, hoping reflux clear.
Best Wishes,
