Hello. We've been together for almost three months now. A couple of days ago it feels like my nose is stuffed up, my voice is hoarse, I have a cough and I often cough. We saw two pediatricians, they said that the baby is generally healthy (obviously such doctors!!!). But I hear clearly that the baby breathes and cries differently than before. Can you tell me what to treat?
