Poorly babies 🤮🤮

Siera

So I’ve got two children. 7&3 both are poorly. Barely going the toilet. Haven’t eaten since yesterday breakfast, still been drinking but they’ve just slept the entire day away since around 12:30 yesterday afternoon they’ve not stayed awake for longer than an hour at a time. Really hot and neither of them will take medicine. Is this just a normal flu or is it worth a trip to the doctors?
