4 year old only weeing once a day

Is she potty trained? If so, I would make her go pee if it's been a while. We have to do this with me son. X

Is she drinking enough? Idk I feel like that’s the main thing I’d check

My 4 year old does this. She has a bladder of steel! She defo doesn’t drink enough and I’m constantly encouraging her to drink more. Sometimes she’s just too busy to remember to wee and other times it’s a power thing - she won’t go because I want her to.

I'd be making sure she's drinking enough THEN consider seeing about it.

Monitor input and output.

Sounds like she needs more water. If she won't drink water, try adding fruit pieces, adding ice, getting a cool cup. Or offer cucumbers, lettuce, tomatoes, watermelon etc to up her hydration

I was this kid! I distinctly remember it doing my mum’s head in but I just was never thirsty? I also hated using public toilets / loos at school, and cups that were too big (I don’t remember why really, just that there was pressure to drink it all - I was an anxious kid) so my mum would give me a ‘special’ tiny cup, it was like a morroccan tea glass I think, so I felt less pressure to drink huge amounts but naturally would over the course of a meal x

My 4yo has done this off & on for a couple years, it stopped as soon as he quit peeing the bed. My now 16yo did similar, but he’d at least go if I said something, our 4yo wouldn’t even go first thing in the morning. He quit peeing the bed a couple months ago, also nothing was wrong with him, just apparently learning how to hold it for 12hrs at a time so he could quit using underpads at night, cause now he’s throwing a fit if we try to use them in case he has a wet night, got so mad about it a couple nights that he actually went in his room before bed & peed on 3 of them on purpose, to get his point across. 😬
