Bangs can look really cute on little kids.
But.

I spent most of my childhood growing my bangs out in two stages. At the age of, I dunno, eight or so I realised that whoever cut my bang had been cutting further and further back each time, so instead of the bangs being a fringe along the hairline they were this huge triangular wodge of hair starting from practically the back of my head. I think I had more hair in my bangs than in my ponytail! So I grew out the back couple of inches, to make my bangs regular bangs again. Not fine and wispy, just not that horrible triangle of doom.
That took AGES. I had these really ugly clips to push the growing-out bits back and they were always popping out and getting tangled in my hair.
Then when I was 13 I decided not to wear bangs any more at all (coincided with quitting wearing glasses, plus I grew a lot that year, so nobody recognised me the next year!). So again, painful awkward growing-out process. I used a headband that time, which was equally ugly and awkward.
The whole process took YEARS, and I feel like I spent most of my formative years struggling with recalcitrant hair-wrangling devices.

So, while I think DD would look cute with bangs, I'm avoiding them just so we don't have to deal with the drama later. Even "mild" bangs, with just a few millimetres'-worth of hair back from the hairline cut into a fringe, tend to creep backwards after multiple cuts until you end up with a chunky fringe.
Plus I had a cowlick, which used to drive me to tears because it would never lie down, so I had this permanent silly loop of hair sticking up on one side of my bangs. When I finally grew my bangs out and the hair started meekly sliding into a ponytail, it was like magic.

Bangs + cowlicks = evil.
