(1) At this age, or by this age, usually, a child is pooping fairly reliably at around the same time or times every day, usually 15 - 30 minutes after a meal and/or 30 minutes after waking up in the morning. If that’s true of your daughter, then set the potty bell to ring on that schedule. Anticipate! Be proactive, but be careful not to begin micromanaging.
(2) Once you’re over the hump at home, this new skill should transfer quickly to day care, but they ought to be anticipating her bowel movements as well. I bet they take place right after lunch or snack.
By the way, George Harrison wrote a famous song that applies to this process: “All Things Must Pass.” I know, bad joke. I’ll try to do better next time.
