Pee when changed

My daughter hasn't peed while changing her since she was like a month old but on a Facebook mom page I'm seeing a lot of mom's saying their 1 year old girls pee at every change. Is this a habit they start closer to a year old or is it just something some grow out of and some dont? I don't want to ask on there because I don't want the moms thinking I'm trying to put their babies down or brag on mine vs theirs. I just want to know if this is something I should expect later on or not
