I took your observations to heart and set about to make a dress a really baby-baby could wear–Big head hole, no fuzzy yarn, and no little holes for fingers to get tangled in. And, obviously, smaller than the purple dress. I bring you the blue dress.
So, it’s much less frilly and I went with a half-double crochet rather than a double crochet on the bodice so that it’s more solid. The skirt is worked sideways–ten single crochets and ten half double crochets to give it that flair and you attach it to the bodice with a single crochet as you work it. It’s tricky to get at first, and then it’s really easy and makes a solid attachment. The only thing I think I might do differently next time is to make fewer single crochets every other row so that the flair is a little more pleated.
This is the back except for the buttons, which will lie flat on the back. I’m worried about this not being 100% comfortable, but I think only fasteners at the top of the arms could overcome that. Anyway, the opening goes clear down to the skirt to give plenty of room for small-baby manipulation to get it on.
And here’s how big it is compared to the other dress.

Very nice!
Meant to comment on the purple one the other day but WP didn’t like my browser and bridgett covered the bases pretty well. Excellent job making it more baby friendly. My only comment… buttons are not a parent’s friend. My kids’ first words were nearly swears because they heard me curse buttons so many times when they were little. It’s hard to button up a wriggly baby. Maybe that’s a dad thing or a ‘my fat fingers thing’ cause my wife was always much better with it. The big opening for cute lopsided heads is a good trade off too.
So I guess there’s no point to this comment other than realizing I tend to ramble early in the morning…
