I went through this in the 1990s as a single dad of two daughters.
Back then it was all set up for women only, thus the only place to change nappies was in the women’s place set aside for mothers and babies, don’t remember what it was called, but men were not allowed in there, so men had no where in town to change their daughters or sons nappies, and i would have to drive home if the girls needed to go to the toilet when older.
