Hi my little one who is 3 months but tiny so more like a one month old has got laryngomalacia so her breathing is noisy. Recently her breathing episodes have got worse and sound like her nose keeps blocking and swear she is having pauses in breathing when awake aswell as asleep and struggles to breathe through her nose. But always seems to be fine when she is getting checked out. Her lungs suck in and belly comes out and done videos to show but she isnt doing any of it when get checked out so not being taken seriously. she also hss bad reflux, and on meds to help with it. My question is, his there any baby oximeters from 1 month old plus that don't cost too much so I can keep an eye on her oxygen levels and possibly record the proof of that if there is dropping oxygen levels. I know you can get pediactric ones but most are 1 year plus.
