Christmas pajamas after Christmas?

So my kids both have birthdays a little bit before Christmas (October and November) and every year they get Christmas pajamas from both grandparents, and they basically wear them until they grow out of them (so after Christmas)

My kids don’t really have a lot of pajamas, they are really soft and comfy, and they don’t wear the same pajamas 2 nights in a row unless they’ve been washed.

My husband thinks it’s weird they still wear Christmas pajamas after Christmas. I never really thought anything of it, they are just pajamas

Am I the weird one? Or is it weird to wear them after Christmas?
