Hi my DS 3.5 has tracheabronchial malacia, now classed as mild/moderate down graded from servere. We too had such a rough go with O2 at home, pulseoximeter, trial CPAP
, many admissions, sleep apnea, pnumonia, bronchilitis, bronchial lavarges (helped with the excess fluids on the lungs) etc etc.
It's a horrible condition to nurse a sick child through. Unfortunately our DS will have this condition through out his life as his is related to a genetic condition which has only just been picked up. Before that we too were told the "wait and see" grrrrrrr
Even when he was having what they call "death spells" and regressing in his speech and gross motor skills we still got the same line and shipped around pretty much every dept at the hospital.
Thank god we now know what the cause of it all is. Ehlers Danlos Syndrome.
I know how hard it is. And I feel for you and your bub.
Only advice I can give is document everything like Haley mentioned. Ask if your child can trial a drug called Singular. It helped us greatly with the extra fluid on the lungs.
Does your child turn blue? Have mottled skin? This is the main concern which means that further investigation needs to be done.
Also ask if you can also trial a reflux med. It may help. My boy used to vomit alot as well. And yes I was told its very common with this condition.
