Toddlers morning wees suddenly stink!

[cosymama]

My 2 year and 3 month old has this week woken up with the stinkiest wet nappies she’s ever had. They smell absolutely revolting, like week old pee is the only way I can describe it. We are having to shower her in the morning and wash all bedding every day, and air her room out.

Nothing about what she is eating or drinking has changed, same nappy brand being used throughout, we obviously took her to the doctors in case of a UTI and that’s come back normal. We have been potty training for about a month with lots of success with the wees and a few issues with the poos.

I don’t want to sound like a ridiculous worried mum posting about morning pee smelling because I know it does, however this is new for her and it is so pungent and come on out of nowhere this last week. We are filling her with fluids more so than normal and all her pees in her potty in the day smell fine, it’s just the morning one. Anyone come across this before with their own little ones?

Does her breathe smell on waking or smell sweet and sweaty with the stinky wee? My first thought was ketones (I have a a child who has test strips and glucose monitoring). How is she generally and is she drinking and eating enough before bed?

If they were present in her wee would they be there all the time? The sample I got from her was the second pee of the day and came back normal?

Bad smelling urine is normal from many vegetables such as asparagus. It’s not dangerous just look at why she’s eaten

My son has Ketotic hypoglycaemia so he produces ketones after periods of fasting (so often first thing in the morning). He drinks so much though that his wee rarely smells of anything.

His twin has really stinky morning wees now (almost 3) and doesn’t drink as much so this may be why.

My DD used to have incredibly ammonia-smelling wee in the morning - that first nappy could give me an instant headache. I just gave her a bath every morning to get the ammonia off her skin, and it stopped after a while. I don't think it's anything to worry about - some wee just smells worse than others.

Thanks guys, changed nappy types across the week and they are still stinking.
Dehydration wise, she's so full of water! She's a good drinker anyway but we've been ON. IT. all week, especially before bed and they are still smelly! It's so weird!
And no asparagus has been eaten, no changes to her usual diet in the slightest.

An antibiotic did this to my toddler but only lasted several days x

I think there's a hormone change that makes urine more concentrated overnight (which is often when they start going through the night not needing a wee). Sorry, I'm not explaining myself very well. I noticed it about this age too. DS would have one very stinky morning nappy, and the rest would be normal.
