I say GO and have fun! what better way to spend the holidays introducing your family to the newest member?? Make sure to carry sanitizer and be prepared to make plenty of stops along the way for feedings and burping, Newborns sleep ALOT so it should go pretty smooth, and make sure the family knows that they have to wash. I would be careful passing baby around too much in a day though, because sometimes it makes them sore and fussy, but i think you would have a good time, not to mention all the extra hands to help when you need a rest too!
