periodic occcurance of asthma in child

I have a girl child who will turn 2 years in September. We are from Kerala in India and the climate at our place is humid most of the year (and our place is relatively close to the sea - 3 km). I am giving my daughter's medical history below and the current asthmatic symptoms.

Child's medical history
------------------------
6 months after birth she developed what seems to be a case of atopic eczema. We went for a homeopathic treatment with a doctor and she got cured of all symptoms in about 9 months. This would be around October 2007.
In early december 2007, she had her first wheezing attack following a cold and cough sequence. The weather at my place was turning cold around that time and there were unseasonal rains and damp climate. We were caught off-guard and she had to take an allopathic treatment involving anti-biotic (Topcef), asthalin syrup, betamethasone sulphate oral steroid for 7 days. She became fine and we talked with our homeo doctor and started a course of preventive for her by early january, 2008.
She again started another round of cold, cough round in mid/late Feb 2008 and we followed up with our homeo doc every other day and she was given some other dose of potential wheezing preventive and she didn't develop a wheezing attack.
In the later half of March 2008, she developed what seemed to start off as a dry cough. The weather was again wet as there were unseasonal heavy summer rains. We were careful and again started visiting our homeo doc every 3-4 days and she was on medication for the cough. The cough persisted for about 2 weeks and then suddenly it turned worse and the child would cough every few minutes and she was becoming weak and most of the time will only lie in the cradle or mother's lap. We consulted our allopathic paediatrician and she went through 2 rounds of antibiotics + asthalin + betnasol (oral steroid) in about a week. But she was not getting better and the doc said that the infection had become a lower-respiratory tract one and we consulted an allopathic paediatric pulmonologist. She underwent 1 week of oral medication involving Ventrolin (salbutamol), Betnasol and an antibiotic for lower respiratory infection. She was fine by the second week of April 2008.
In mid June 2008 she again developed wheezing symptoms accompanied by cough following an attack of cold. This time too we had consulted the homeo doc initially, but the wheezing tendency was not detected and we again had to go for the allopathic treatment involving the last mentioned medicines, but for a shorter period of 4 days.
Last week, end of July 2008, she again developed cold symptoms with sneezing following Viral cold attack (many of us in family had one type of viral infection, fever or cold). This time too the climate was rainy, but it was part of the monsoon at my place. Even though we consulted the homeo physician at the onset of cold, she caught wheezing. This time she is recovering after about 4 days of allopathic medication involving Amoxicyllin, Asthalin syrup and Predone syrup (corteco-steroid).
The paediatric pulmonologist suggested putting her on a 3-4 month preventive course of Montelukast, but we have not yet started that hoping that we can do something with homeopathy itself.

Parent's medical history

Dry skin.
History of childhood asthma (till about 16 years) mostly developing following an attack of cold.

History of asthma from 9 years and continuing. Currently on Seroflo 125 inhaler once daily. But has not been using it daily - able to manage with on the average once in 4-5 days in the past few years. Has been trying homeo treatment for the past 1 year (without any break) to move out of inhalers. Not really successful so far.
Father has a history of persistent cold and regular sneezing in morning. Allergic and cold prone, especially in humid conditions and in dusty places.

We would like to hear from experienced homeopathic practitioners as to what we can do to help our child.
