#AskTheExpert hello doctor, my baby is 5 month old and used to sleep for 4-5 hrs at a stretch (sometimes even longer) at night followed by 2 hrs sleep twice. but of late he has started sleeping for lesser durations and wakes up every 1-2 hours at night. daytime naps are the same pattern as before- around 3-4 in number which are either for half hour or 45 mins. Is it ok? I have heard that as babies grow they tend to sleep longer at night. please advise
