Just a bit concerned about ds. He's 11 months and has been very off today, mostly sitting having cuddles, being bf (right now, one hand typing!) and sleeping. I've just tken his temp and it's 39.7. I have an 8 yo dd who was suddenly sick on saturday night, again on sunday morning, and has had a temp and headache since. Is it likely the same thing? Ds hasn't been sick at all though did hae a bit of a nappy explosion this afternoon. Is it best to strip him down to cool him off?
