i think you made the right choice. ive done it about every way, shot does with small yearlings, shot yearlings with mom, shot mom and yearling together but this was in my first several years of hunting and I was not picky about what I chose to take. I'll admit though I have become a softy now in my 6th year of hunting and I let does with fawns walk no matter what time of year I see them or how old they are.
I still think about times Ive shot momma and how the yearlings acted afterwards. Just last year i took what I thought was a lone doe but soon after I shot when I got out of my stand I walked up to her with her 2 yearlings no more than 15yds away just staring at her wondering what was happening. Now days I'd rather just watch them, I dont think theres anything more interesting to watch in the deer woods than a couple yearlings playing around.
