DH travels occasionally for his job. Usually this is nbd because I have a very flexible workplace and I just shift my hours so I can do dropoff and pickup.
Often there is not much notice that he'll be away. For instance, he just emailed me to say he needs to go out of town Sunday night or Monday morning and will be back Wednesday. Well I have a big presentation to give after work next Wednesday at a city town hall event. Can't get out of it. Wouldn't want to anyway.
DD attends full time daycare and needs to be picked up at the exact time my presentation starts. We have no family in town and our regular babysitter went back to college in August. Two other attempts at getting a new regular babysitter have resulted in (1) a no-show and (2) a last minute cancellation. So we don't have anyone right now.
I've told DH to see if he can get back Weds in time to pick up DD. (His trip is only 3ish hrs away) if that fails, what would you do about daycare pickup/ dinner coverage?
UPDATE: DH is going to leave earlier on Sunday so he can start work Sunday eve, then travel back Wednesday morning. Should be back with a couple hours to spare before pickup time. Phew!
Thank you so much for all the ideas though. I will ask some of her daycare teachers and post in our neighborhood FB group. It would be nice to be able to go on a day every now and then!
