S.B.
We travelled a lot and as a result, from a very early age, my kids could sleep anywhere.
We never would have survived or been able to leave the house if the only place the kids could nap or lay down at night was in their own beds.
My son was only 3 weeks old when my mother in law passed away and we were away from home for two weeks staying either in our hotel room or my in-law's house as we planned the funeral service and handled their affairs.
It might not seem like the optimal conditions for sleeping patterns especially when life didn't exactly allow us exact and specific times to hold rigid to, but ironically, my kids were always excellent sleepers.
We could travel and take them anywhere. And we did. It was normal for them.
I guess the point I'm trying to make is that I understand trying to adhere to sleep schedules, but experiencing something outside of that routine once in a while might help them be more adept at going with the flow and doing okay in different situations.
No offense, but I do not think it's realistic to expect everyone else to change things according to your children's sleep or nap schedules. Bow out gracefully if you choose, but realize that time marches on and the world keeps spinning and our kids to an extent have to be allowed to learn to function as opposed to thinking the rest of the world should come to a stop or alter it's path for them.
This is just my opinion.
