Dd is 4 months old. She has started shaking her head like a shudder every so often and it is worrying me. I saw a programme a while ago where a baby had similar behaviour and they said he was epileptic. I'm the only one who's seen her do this as it doesn't happen very often. Does anyone elses baby do the same? Not sure if I should go to the doctor as they won't be able to see it happen.
