Thank you for your query on Healthcare Magic.
Examine for any signs of injuries due to fall like any swelling, bruising, and for bleeding points on the body.
Watch for vomitings, abnormal behavior, persistent crying to look for any head injury
and if you find any abnormality consult your doctor immediately.
The loose stools are due to some contamination by keeping hands into mouth.
Maintain hydration by giving sips of oral rehydration fluids like Pedialyte
Consult your Pediatrician
if the loose stools persist.
Hope I have answered your query.
