I bought a July 2013 build car this past Memorial Day. It started out with about 18 kWh at full charge. Over the summer I was getting 5 miles per kWh easily on the worn original tires, and at that time I could easily go 60+ miles before hitting 25% SOC in careful(ish) city driving, or at constant 50-55 mph freeway driving (all fairly flat routes, but not perfectly flat).
I replaced the tires in September with new Ecopia Plus and took a 10% hit with the stiffer, heavier new tires. Still would be pretty close to workable for your commute without white knuckles.
But, in the last month as "winter" weather (Seattle winter, so you know, NOT really winter), my range has tanked due to using heat, defogging (not optional!) and lights and wind and rolling on wet road, which apparently all matters although you never notice it with an ICEV. I can basically rely on getting 3.0 miles per kWh (I just got back from a 13 mile round-trip taking the kid to a sport class for which LeafSpy said I got exactly that mileage), so now I can go just over 40 miles from a full charge to 25%, or if I wanted to keep it between 80% and 30% SOH for best battery life, that would be 27 miles per cycle. My hope is that it will be 5 or 6 years before the car drops the 9th bar (to SOH 65%) and so gets less than about 80% of these values.
So, for your kid's current needs, you are good to go, but for your commute, winters will be marginal, at best, if you can't charge at both ends (or jump on a nearby DCQC conveniently). The commute would probably be do-able in summer for a couple of years.
