Half birthday celebration

I’ll start by saying please no negative comments!!

My husband and I want to do a little celebration for our daughters half birthday. We feel like this is a big step for us because I feel like half the time we didn’t think we’d make it (she’s beyond hard). I’d like to do something just for fun. She’s been eating solids for a little while now so I was wondering about doing a mini cake. I’ve looked up some healthy recipes but I was wondering if anyone had suggestions.

Thanks in advance and please no negativity!
