Toddler boy urine smell

Hay, I haven't experienced that myself pero one of my mum friends noticed something similar with her son and turned out it was just because he wasn't getting rinsed properly after diaper changes, the urine was sitting on his skin. I'd suggest making sure you're doing a gentle wash with water every time, lalo na pag mainit at humid, kasi ang bacteria doon talaga nag-thrive. But honestly, if the smell is really strong or persistent kahit after cleaning, better check with the pedia just to rule out any UTI or infection, kasi di yan normal sa healthy toddlers, better safe than sorry dito.
