Dear Sibandembali, hello
Young children are prone to recurrent infections especially upto 5 years due to low immunity. If your daughter is having bronchitis
she is allergic to cold
and will face the problem whenever there is change in season. Foul smell breath may be due to some secondary infection of the upper respiratory tract
during allergic episodes of cold.
Try to take precautions whenever season changes. Give her fresh fruits and vegetables as they are protective foods and help to develop immunity. Also encourage her to drink plenty of pure filtered water .
Teach her the habbit of always washing hands before eating anything whether in school or at home. This will prevent majority of infections.
I hope your daughter if fully vaccinated according to her age.
I hope this is of help to you. Thank you and take care.
