Family wants us to come to them for holidays a month before having third child

Hi guys. So my husband and I are usually the more go-with-the-flow ones in my family and usually travel to my parents' house for pretty much all of the major holidays. Apparently we've unfortunately set this as an expectation the past few years and despite what discomfort this could cause for us, they're having an extremely difficult time accepting the fact that this year they need to be more flexible (my adult sister and dad in particular).I'll be about four weeks from being due with our third child at Thanksgiving, and we have a 4 year old and 2 year old. We've already established they will need to come to us (rent an Airbnb, stay at our place, whatever) for Christmas, which already has my dad saying he doesn't want to be traveling in "winter" (It'll be more winter around here mid-January though). But it came up that we don't want to do a big trip like that for Thanksgiving either. Instead of sitting in metro-area holiday traffic with toddlers, an extremely old dog, and uber-pregnant me and then sleeping on either a fold-out couch or inflatable mattress (again...while very pregnant), I really need a month at least of just being chill and resting, prepping our home and business, not being a stressed-out introvert, and not being expected to do everyone else's bidding right before going into labor and adding yet another newborn to the mix.This seems completely reasonable to me and my husband, but all my family seems to hear is "OMG You're not coming for the holidays?????". Cue drama. Those of you who are often the family "peacemakers" - how do you establish better boundaries here and/or also deal with not feeling guilty for taking care of you and your family's needs when you have aging parents who expect you to show up?Would love your thoughts. Thanks in advance.tl;dr: Parents and sister upset we don't want to travel to them for Thanksgiving with toddlers and me one month away from having third baby. Being the family peacemaker kicking me in the ass. I'm already exhausted ya'll. via /r/Parenting https://ift.tt/2L7NObV
