I have a co-worker who is having triplets and want an idea for a baby shower cake. I have some time.. they're not due until the beginning of the year, but I'm planning ahead.
A B C blocks (because generally when you're pregnant with triplets the doctors refer to them as "baby A" Baby B and so forth, could be a cute play on that?
pea pod cakes are really cute. I've made them for singles and twins. It would be cute with triplets as well.
