Hello everyone) Girls, the baby has a cough, dry-ish. There's no fever, there's a wheeze in the chest. But the wheeze was also present before the cough since birth, if I'm not mistaken. Yesterday he was very fussy, wants to sleep but doesn't, wanted to be held constantly. Snot running, biting toys like he wants to eat it. Could this be signs of teething? And could teething cause a cough? What should I do about the cough? To the doctor only on Thursday.
