When my son was little, his father and I went through a custody trial and agreed on a holiday-sharing schedule. It outlined that if my son spent a holiday with me, the following year, he would spend that same holiday with his dad. So if I got Christmas Eve and Day with him one year, the next, his father would spend those days with him.Initially, my son's father and I stuck to the original holiday-sharing schedule. I observed that while my son never had a preference for who he spent the holidays with, he did miss the parent he didn't get to see. After a few years of splitting holidays up, I was compelled to work with his father on a better arrangement. While it doesn't always work out perfectly, we have found that it's best for our son to spend time with each of his parents on any given holiday.We do our best to come up with a plan that works for the whole familyOur new arrangement is informal, and I think we each try to work with each other based on what's going on with our respective families that year and how we divided up the holidays the year prior. While initially we had every holiday divided up until my son turns 18, I think the way we work with each other now is far more realistic.One downside to co-parenting around the holidays is that I always have to tell other people that I need to talk to my son's father before we make any definite plans. Sometimes, I've wished I could just book a vacation over the winter break. However, I've realized that not only does his father deserve to spend time with his son on the holiday as much as I do, I know our son prefers it that way, too.My immediate family understands that I may not have my son for certain traditions, so they factor this in when they're making their plans. They will ask me ahead of time on which days or times I'll have my son; not only are his father and I working together to make sure my son gets to see most of his extended family, but our families do their best to work with us, too.

Courtesy of Ashley Archambault It doesn't always work perfectly, so there have been exceptionsThere are certain holidays where the division is an easy decision, such as Thanksgiving. Growing up, I always liked watching the parade in the morning. Every year, I had an aunt who would suggest we just eat our pie for breakfast, but no one ever went through with it.When I had my son, I had the opportunity to make our own traditions. So now, he and I make pumpkin and apple pies the night before Thanksgiving and then have some for breakfast the next morning while we watch the parade. Since his father's family has a big dinner in the afternoon, we usually just split the day in half so that my son is with me in the morning and with his dad in the afternoon.It might not be a perfect system, as my son is missed at our family's dinner on Thanksgiving, but after co-parenting for a decade, I've come to accept that his father and I always need to work together to come up with a plan that works best for our son, even if that means dividing up every holiday. Sometimes it doesn't work out, so we've learned to address every holiday individually.Last year, my son's father wanted to take him up to New England to spend a week with his family that lives up there, and I was hesitant. My son and I had never spent a Thanksgiving apart before. When I asked my son if he wanted to go, he was excited. Not only does he rarely get to visit with those family members, but we live in Florida, so he had never seen snow before. I made sure he understood that he and I would spend Thanksgiving apart, and while he was sad about that part, we agreed that because it was a special opportunity for him, he should go.Our new agreement feels rightThis year, his father asked for Christmas Eve since I had my son for Christmas Eve last year. Then, my son will come home Christmas morning and spend the rest of the holiday with me, which is what he did with his dad last year. While I love to have my son on Christmas Eve, it's nice when I have him on Christmas Day, too. After spending alternate years without him on either of those days, I think our way of dividing up the holidays works out so much better.Not only do we each get to share our traditions with our son every year instead of every other year, but my son can count on spending the holidays with both of his parents. It's always a little sad for him when he is separated from one of us, and that emotion is amplified on holidays. But I think it comforts him to know that his father and I will always work together to make sure he doesn't have to spend the holidays without seeing one of his parents.
