We started using EFA Blend for children in august, before school started, and used it up to Christmas. About a month ago his teacher noticed some slight twitching and drooling, and also some long stairs into space. Just before Christmas he had two seizures in his sleep. After reading up on seizures we found that the long stares and drooling could have been seizures also. We have stopped giving him this product and the seizures have not returned yet. I'm not really sure if this was the cause, but my son never had seizures before taking this stuff. Be careful of what you give your child and ask a neurologist about anything that affects your childs brain.
