My 7-month-old son got asthma may I know which foods trigger asthma? is it normal to get asthma at this age? please suggest

A. Hai good afternoon !! Mostly the weather cool weather rainy season,winters,when they expose to cool breeze,snow . Food likes fruits banana,orange ,curd at evening ,night worsens . So consult paediatric doctor and ask suggestion on food as baby is 7 months old you also need to check suitability of food item too.
