<s>[INST] Hi.I have got a 9 month old boy who has turned out to have a lot of sleeping difficulties,since i started him on solids.he used to wake up 3-4 times a night,now he wakes up more than 10 times a night.Could it be because he is intolerant to something or is it something else? [/INST] Hello,Disturbed sleep in a nine-month baby usually due to hunger or colic. Feed him during nights, start some antispasmodic medication like Colic acid. It doesn't belong to solid food. Also look for a nasal block, if any then clear blockage with the saline drop.Hope I have answered your query. Let me know if I can assist you further.Regards,      Dr. Sachin Kumar Agarwal </s>
