I live in the 19th district of Paris—probably the cheapest district within city bounds, with the 20th, and not in the center—and I have no issue living with an under 2-year-old. Hell I even decide to go all the way to the 14th for his pediatrician appointments, on the subway. I can walk to something like 5 supermarkets and bodega-like markets, take the subway to a bunch more including specialized, I can walk to see a generalist, we walk to his daycare, etc. all < 10 minutes. I can’t imagine what you can’t do honestly.
