Has anyone's child(ren) had the norovirus? My son has the symtoms, started last night projectile vommiting and watery diarrhoea. He is not keeping anything down, not even water!
Give him dioralyte in a little water to sip. You can get it at any Chemist and it will help replace lost salts and sugars. When he is ready you can try some dry toast but he probably wont be hungry for a while.
Its usually over in 24 - 48 hrs.
Good luck!
