Thank you for your query,
You told there is no mark head and soft spot, so nothing to worry.
The trauma by a feeding bottile while shaking will be minimal and doesnt have caused significant injury
to the child.
Watch for her activity, feeding .
If every thing is good, activity and feeding is normal and there is no cry, nothing to worry.
If you find any difference, consult your Pediatrician
Hope i have answered your query.
