15 week old - odd smelling breath

[OhWhatAPalaver]

Dd's breath is smelling slightly unusual today. Kind of sharp smell, vinegar ish (dp says rhubarb) she is also very windy, as I've described in my other post a bit further down.
I'm a bit concerned about the sudden onset of this, has anyone else experienced this? Could it be reflux or something else? Thanks.

I'm not sure how to describe the exact smell, but the first sign that DS had tonsillitis was odd smelling breath. His smelled quite unpleasant though, sort of 'infection-y' if you know what I mean.

I think keytones can make breath smell fruity though.

Mine get smelly breath when their nose is blocked and always have done but I can't describe it, it is subtle but there

What are key tones indicative of? Nothing bad I hope?

[OhWhatAPalaver]

It is quite strong now but not really infection-y I don't think...

My kids get this just before they're ill - usual kids illnesses - nothing horrendous

Mine had this and it turned out to be thrush.
