My son has been constantly poorly since being born always catches all bugs but knocks him off his feet which alot of time ends up in hospital for several days. he started with bad colic and then febrile convulsions. in and out of hospital. he’s now 4 and although hasn’t had a convulsion for several months has now been told he has viral wheeze. Asthma. still catches every bug going and has viral infections frequent. never a full month without him being poorly. under consultant and regular at the docs which both say he’s just one of those children and Will grow out of it around 5. he’s on steroids inhaler and blue. also antibiotics at the moment with pain relief. is there anything i can do to help with maybe his immune system to try to help prevent so many frequent eppisodes??
