How long do parents usually refer to their child as “… months old” vs. “…years old”?

Because I need to know when it will be unacceptable to celebrate our month-a-versaries.

Most people celebrate there wedding day once a year but what fun is that?  Instead, we {or maybe just I} decided that we should celebrate each month!

I’m not sure how long we’ll keep this tradition up but for now I enjoy writing/seeing it on our fridge calendar and finding different ways to celebrate the newness of marriage!

Do you celebrate month-a-versaries?

p.s. – fun fact: I’m 324 months old!
