My baby was sleeping for 7 8 hours continue at night. But for last 10 days he is sleeping for 3 4 hours than woke up than again sleeps for 2 hours. Why his sleep suddenly decreased?

A. Initially sometimes kids sleep for longer duration with her progressing age when they’re hunger increases they wake up from time to time to take a feed and go to sleep which is very natural practice so there is nothing wrong in what this is common to be seen
