Why does my kid get frequent colds?

Hi doctor,

My 4-year-old daughter is frequently suffering from colds. In turn, she develops a bacterial infection. In the last three months, she has had six bacterial infections. Her doctor gives her antibiotic medicines. She has a chronic cough now, and Budecort was suggested for three months for Asthalin if she coughs. I need to know why she has frequent colds. The doctor suggests it is allergic, but no idea what. There is no family history of asthma. I am worried about my daughter. She has developed this after two and a half years of being healthy.

Does allergic could happen due to the local home environment? My flat is on the first floor and near a hill. Nights are extremely cold. I have an oil-filled room heater. My kitchen has some leakage, and a fungal smell comes out. Is this the reason for frequent allergies? Please suggest if I need to change my flat.

Thanks doctor,

Dust mites are not there. Some kind of smell is there due to wood burning, but that is not regular. Shall I add a HEPA filter in my flat, at least in the bedroom? For cold weather, I bought an oil-filled room heater. Montair 4 mg tablets are already there; I forgot to mention. If her health issue is local, how can I medically stop this? As it is not possible to relocate somewhere else.

Currently, it is summer. Still, she has a cold, even though it is not too cold outside. Last year, we did allergy testing, but IgE is not showing any allergic reactions. She usually breathes through her mouth at night. Her adenoid X-ray also suggests they are not big in size. Shall I try with an a/c and HEPA filters to keep the room smell free and pollen-free? Or, should I wait until she turns 6 so that her immunity becomes better? Does the hillside have more pollen and pollutant air than the plains? Previously, we used to live 1.25 miles from our current home when she was 2 and a half years. Until then, no such health issues were there. After that, we moved to a new flat, and she had a constant cold. Please suggest better options apart from moving to another place.

Thank you, doctor,

Inhaler Budecort is two times, Asthalin if cough, Allegra syrup if cold for five days, and Montair 4 mg tablet for three months, one tablet at night. All the above medicines are for two months. This is the same treatment we did last year as well. In recent months, she has had a regular fever. She had simple febrile convulsions six months back. My point is, how to build immunity? As each week sickness is too much. I am giving Allegra and an inhaler almost every week. Does this impact badly as side effects? Allopathy seems helpless to address this issue.

Hi doctor,

Thank you for the reply.

A good point to note is dehydration. It means we can give more drinking water. Is there any measurable unit of water?

She mostly develops bacterial infections and needs antibiotics. The point is that the bacterial infection plus fever and then medicine continued till the fourth of this month. Yesterday, she got a fever, that is, on the eighth. The same thing happened last month as well. Why repetitive bacterial infections? Can it be due to food? She had convulsions last year. Is the fever due to her medicines? We started using Fresium tablet as well two tablets a day.

The pattern is cold, then cough, then fever, and asthma symptoms are extra. If she has a cold, then for how many days to give Allegra? Does my daughter have side effects of antibiotics used frequently (two or three times in a month)? For hydration, what extra to give?
