?benign non epileptic form movement disorder , ?benign myoclonic of infancy

Hello, my eleven month old son has been having jerk for the past one month.They started abruptly one evening while feeding porridge to him.Some are as simple jerk in his one arm sometimes both arms with a single,otherwise two or four fire in a row.
  Since they began he has two EEGs and an MRI.All have came back clean.The EEGs did not indicate there was any loss of consciousness as is typical of epilepsy ,and the MRI without contrast didn't indicate any abnormalities. The neurologist believe they are benign and hopes that they will go away over the next few months. However he has 10-20 a day.It makes him more tired. Doctors official diagnosis is benign myoclonis of infancy and another says it is tics. Have you experience with anything similar ?should we get second opinion?We're worried about it devoloping into severe myoclonic epilepsy or something similarly scary...
  His development is very good but only this problem. How this came to my son  ? What is the reason or cause for it? Whether it will be cured or not how it can be cured?
   Nw we giving drugs valparin and lonazep....
  Please answer for each and every question. ? Any how we have
