Boob cake?

So lately (not on this app), I've seen a lot of parents posting pictures of their child's first birthday and the smash cake is a boob. And they always put some kind of caption about making it a year breastfeeding. Does anyone else think this is odd? I've breastfed both my kiddos. And although I do consider it an achievement, I feel like it's kind of just a "Pat myself on the back and say good job for not giving up" kind of achievement. A children's first birthday is about them, not about the mom. It's a celebration of a year of life, not a year of breastfeeding.

Some of these cakes are super detailed and odd. Haha. I don't know, I just find it odd, but was wondering if I'm just being a hater maybe.
