hello good evening, by the symptoms you have told , your child may be having a hyperactive airways thats the reason he is getting frequent cold
. wheeze and cough. the abdominal pain
may be due to repeated cough which causes abdominal muscle spasms and pain. I would suggest you to review with your pediatrician
and get your child examined and have full knowledge about asthma
, its treatment and methods of preventing it. thank you.
