What Causes Disturbed Sleep And Fatigue In An Infant While Recovering From Diarrhea?

Question : I have a 7month old girl baby & she has been having very disturbed sleep from last few weeks. It all started after we went out for a trip involving road/train/flight travel in last week of March. During the trip we dint observe any issues , however once we came back home. Baby started having loose motions, loose motions went on for atleast 3 weeks & we consulted a local pediatric who advised Taxim syrup(for bacterial infection treatment) for her 5 days .After 5 days when the loose motion dint stop, we waited for few more days & then doctor asked us to start with Taxim dosage for another 5 days, after which the loose motions subsided. All these days she was having very disturbed sleep & would continuously seek feeding through out the night, Now even after her initial illness is cured, she is still with the same habit of not getting a continuous sleep at night. As soon as she goes to sleep within 20 mins she would start crying for feed & after feed would go off to sleep again. But the problem is every 20 -25 mins she keeps seeking feed & this continues through out the night. In morning as well she doesn't sleep continuously for more than 30mins, when she is awake she is playful & doesn't show any signs of fatigue or illness. Please suggest on how can we correct her habits or get her to a good peaceful sleep.

Hi Doctor thanks for your response, however we are most concerned about she being sleep deprived. Through out the day she would be sleeping a XXXXXXX of 8 hrs & that too in a discontinous manner. Would this affect her? Anything that we could do treat or get her to sleep more peacefully ?
