Ahhh mama, 19 hari baru lagi, if baby is having cough and cold symptoms, please go to the clinic or hospital ok, especially at this age. Better to check with the doctor to make sure everything is okay and get proper advice. Once the doctor gives you the green light, a few of us mums just do gentle saline drops or steam (from a bowl of hot water nearby, not directly) to help baby breathe better, but must check with your pediatrician first la. Hang in there, mama!
