recurrent sick baby

Sino po dto ang my baby na after mg 1 yr old prang nging madalas ang pgkakasakit ni baby, like allergies, recurrent cough and colds,though never nmn ngkafever, still masigla pa dn.. do you always give medicine to treat those or sometimes you just let it heal alone? Share your experiences nmn po mommies mdyo nkkafrustrate lng po kc khit iiwas cya sa lahat ng bawal and giving healthy foods gnyan pa dn. .
