I agree with the posters saying a quick good bye is the best way to go. Having a parent stay the whole day would be disruptive to the other children. Plus with my group, the kids tend to act out when another parent is there.

Since your provider only has your lg, then I would ask her and explain why you think it's important. I would go into it expecting her to say no or to come back with an offer for an hour or so per day.

Good luck!
