Grrrrrrrr!

If a parent is going to pick up during naptime, I don't wake them up until the parent is at my door!

Yes.... I was thinking this as I read the OP's scenario. On the phone, I would just say, "ok, I'm going to let her sleep and when you get here, I'll get her up and bring her to you." That way IF she changes her plans, no harm/no foul. Baby still sleeping. Also, you don't get a crying, cranky baby who was cheated out of a full nap.

Holy Crapcakes, good thing it was Friday. I would've been very upset and probably not very nice to her at pick-up time. My passive aggressive way of dealing with a parent.
