Hi...Thank you for consulting in Health Care magic.
It seems your kid is having acute watery
diarrhea. Unless the kid's having low urine output or very dull or excessively sleepy or blood in motion or green bilious
vomiting...you need not worry.
Unless there is blood in the motion there is no need for antibiotics or cultures. Antibiotics might worsen if unnecessarily used causing antibiotic associated diarrhea. I suggest you use zinc supplements & ORS. For vomiting you can use Syrup
Ondansetron 0.15mg/kg/dose thrice a day, 30minutes before feeds.
For your kid's cold, you can use
Cetrizine syrup if needed on a once daily basis as suggested by your
pediatrician.
Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Health care magic are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
