Nakakabilib actually, kasi normally bata pa yan for nighttime dryness, at 2 years old, it's usually just holding it or developing ang control niya, especially kung normal ang lab results! A few of us had the same thing, one of my mum friends' daughter was also super dry at night around that age, at eventually nag-normalize lang siya naturally as she grew older. Since the doctor's already cleared her and the tests came back okay, I'd say just follow your pediatrician's advice and hindi na kailangan mag-worry masyado. Mahirap ang potty training season kaya maybe observe lang kung paano siya during day, if she's holding pee, that's normal development din, walang rush.
