Baby allergies??

Holly

Is it possible for a baby to have seasonal allergies already? My LO has pretty much always had congestion - we use the nose Frida about 2x a week for congestion w saline drops and use a humidifier. He seems to have developed a dry cough as well but otherwise healthy, acting normal and no fevers. It seems like allergies to me, at least that’s what it feels like as an adult having those symptoms! Anyone else gone thru this?? Thanks!
