my 8 yr old for the past yr has started getting headaches! sometimes if hasnt slept very well or had a lot of lates nights and early mornings! he starts with a slight headache then is sick if doesnt get calpol straight away and needs a lie down! is it normal for someone so young to have these! 2nd time this yr he has been sent home from school and not allowed in or 48hrs as they think its a sicky bug.
