K.,
I think you have received some great advice and I agree to leave his nose stuffy. It wouldn't be stuffy if he wasn't throwing a fit. It's never good to give into tantrums.
I did want to speak to your question about asking the provider not to give him a nap. That's really a very unfair request of the provider. Her day is automatically at least 1 hour longer than yours with drive time. If she has others that come earlier or pick up later, she may work a 10-12 hour day and still have to clean up before and after and prepare for the next day. That makes the average provider working hard 12-14 hours per day. Not only that, she usually gets up early and doesn't have a lunch hour or breaks. Nap time is the only time she can get off her feet or even think. There is often one or more child thrown off their routine by these family trips which may very well cause her to not get a full nap time and some days, no nap time. So asking her to make a tired child stay awake is really a no no in the daycare world.
