DD waking with wet pj bottoms, but not wetting herself

[TheGoblinQueen2711]

My DD (4) is waking every night with a damp patch in her pj bottoms (won't wear knickers to bed) but her bed is not wet, and I'm sure it's not wee.
Could it be sweat?
Is it something I should be worried about? This never happened with my boys, so I'm unsure if this is a 'normal' thing in girls...
TIA

Just to add, there is no odour coming from her either? So I don't think it's an infection

It could be a pool of sweat in a particular place. Try keeping the room cooler and see if it happens, or if it's just a particular pair of pajamas it happens with...like if they are not cotton they might not be absorbing the sweat.
If she didn't wake, it might have dried by the morning. If you've ever had fake tan on, you come to notice that there are patches of sweat happening that you'd never notice other wise.

I think you'd smell it if is was wee. It probably is sweat.

My DS has this. He sleeps in loose cotton boxer shorts from m&s instead of jammies trousers and he has been better. My DS can get very sweaty at night. There were many times I thought he had done a wee bit due to no smell and bed not wet decided it must be sweat. He has been ok sleeping in pants and vest so far, not sure how he will be in the summer.

So it sounds pretty normal. Which was my first instinct. I think I'm just overthinking it simply because she is waking each night.
I will see if she will sleep with nothing on her bottom half, or with just cotton knickers on and see if it makes any difference.
