Cousins are such a big part of our lives without us even noticing. They start out as the people you share snacks and secrets with at family gatherings, then one day you realize they’re actually the ones who’ve seen you grow through every weird stage.
Some cousins turn into best friends, some you only see once in a while but still feel that same spark when you reconnect. Either way, they hold this special place that’s half-family, half-friend, and it just feels easy.
Birthdays are a nice excuse to remind them of that. Whether you’re sending a quick message, a card, or just posting something with an old photo that makes you both laugh, the right words can make the day feel a little warmer. Here are perfect birthday wishes and messages to send to your cousin.
