DD is 10 and definitely starting to experience puberty. For the last few weeks she has been feeling nauseous (but not actually being sick) on and off. It's really strange because one minute she's completely fine and the next ashen and complaining of feeling sick. You can really see it because she turns pale. Soon after, she will be fine again. I'm wondering if this could be a side-effect of hormones and wondered if anyone had any similar experiences with their teenage DC? TIA
