welcome to HCM
as you describes it seems that your child had minor blunt head injury
minor head trauma
in infant age group is define as a history or physical signs of blunt trauma
to the scalp
, skull, or brain in an infant or child who is alert or awakens to voice or light touch
as you child already seen by doctor and he feel that she is ok then nothing to worry.
do`nt think about long term sequel la as there is no brain injury
then why she have problem;
i think this give you answer.
