You can bring to the PD but the clinic probably do not have medication for babies because they’re too young. If your baby has a lot of mucus inside the nose, try to suck it out so he/she can breathe better. I am using this: https://sg.shp.ee/hNgw8tt (Pricey, but works better than others)
My paed says sometimes GP can check, but if wheezing sound is loud, don’t wait.
Wheezing is already very bad! Means airway is getting tighter too. Go to PD
I usually monitor first few hours, if worsen then grab go urgent care.
