From your description, you are probably having stress
induced twitching and it is not vitamin deficiency
. Electrolyte disorder is possible but to determine that your daughter will need to run serum electrolytes test to determine if there is any.
The twitching is also most likely be isolated and nothing is particularly responsible for it.
You can start by avoiding stressful activities and take sometime to have a good rest.
You can visit your doctor for better evaluation.
Kind regards and hope this helps
