This is a "legal" connection at DTW and it means that DL is willing to accept responsibility for the risk of a misconnect. Whether it is within SCT (Sensible Connect Time) is a matter for OP's judgment.

The issue is not whether the daughter + bag can make the connection if on schedule, but what happens in IRROPS. What is the impact of a 24-hour delay or a lousy reroute? How experienced a traveler is the daughter?

If the fare or something close is available with the earlier BOS-DTW, I would opt for that, make this a more pleasant and less stressful journey and not push the limits.

As for the checked bag, as a general matter, it has an easier connection than a passenger.
