Is this normal for a 2 year old?

So I bought my 2 year old a little potty lime a week ago and she decided to start peeing on the potty on her own with very little to no accidents, which is fantastic! However, she pees small amounts several times within an hour or so. Is this normal? Is it because she has a really small bladder? My first daughter didn’t do this. She’d pee a good amount in one sitting. I’m not sure if this normal, something to be concerned about, or maybe perhaps she’s holding it in and doing it more often for the praise and rewards? Any input would be appreciated.
