I once drove to Canada with 3 kids under the age of 6 and pregnant with the 4th. Got to the border at 2am and they asked why I didn’t have some documentation from my husband saying it was OK to take our kids out of the country. This had never come up before. It had been an 8hr drive to get there…I wasn’t going home to get a letter. I told them to call him and they said they "*didn’t want to wake him up*. Those polite Canadians!! They didn’t have a problem waking up 3 young kids though, to ask them when they’d last seen their dad (earlier that day). When the border agent came around the counter and saw I was 7mo pregnant, she decided no one was foolish enough to be stealing that many kids on their own…which I didn’t argue with. Always had a photo and a letter after that. But I’m curious how you have more than one passport???
