Merry Christmas, LD. A bit late but I've been away from the internet for a bit. We had a nice day... with kids 7, 5, and 2, I have been living in unpackaging toys hell...batteries, unclipping tightly packaged toys, setting up some electronics, setting up even more hot wheels tracks. Honestly I don't mind it (other than the very loud noise of all 3 kids asking for something at the same time) but I know their youth and excitement is fleeting in life, so I enjoy it.
I also enjoy a very subtle pair of "noise reducing" (almost invisible) ear plugs. It's called "Loop", I think. It cuts the volume of noise down about 50% which I cannot describe how much it helps me avoid being an overstimulated dad with a headache.
