<s>[INST] I have a 6 months old baby boy and seems to get a cold all the time, since December to now march, he has suffered from 4 colds and also had bronchiolitis , he gets congested and suffers with a snotty nose which means he doesn t settle well through the nights, he has also never slept through the night due to these colds reoccurring. I use saline nose drops, a vaporiser and a humidifier to help him be more comfortable through the night but still nothing helps. My mother-in-law suffers with her heart, has a very low to nothing of a immune system and has M.E. so I am also concerned that maybe her problems have been passed down to her grandson? [/INST] Hello! Welcome to HealthcareMagic! Have you taken you're child to a pediatrician? If no, better take expert opinion. Children may recover fast but can deteriorate too. As far as grandmother is concerned, has her physician told you she has contagious infection? Two months is quite a long period to treat the child on your own, as it may lead to many problems. Hope that clarifies your doubts. Regards, Dr. Ratna Mulay, Pediatrician </s>
