Too late to send birth announcements?

I got newborn photos done when my twins were 2 1/2 weeks old. It would've been sooner, but Baby A had to stay in the NICU for 9 days. Anyway, I've only gotten sneak peaks of the photos, and the photographer said it'd be a few weeks for the full session to be edited. I feel like by the time I get the photos, pick which one(s) to use for the birth announcement, and then order them, the twins will probably be 2 months. Is that too late to send them? Obviously the whole family knows we've birthed twins by that point.
