Thank you for your query on Healthcare Magic.
Major organ injury with this type of fall is unlikely but observe for any abnormal symptoms or signs.
Coughing or spitting after a fall in your child is not a sign of fluid in the lung.
Look for any increased respiratory rate
, labored breathing
, and shortness of breath
which are suggestive of lung involvement.
Heart injury is unlikely.
Look for any bruising, tenderness on chest and abdomen.
If you feel any abnormality consult your Pediatrician
as early as possible for the examination of the child.
Hope I have answered your query.
