I’m not completely sure about the wisdom of giving a newly minted 3 year old the means to garrotte her baby brother, but know that if there’s any danger her Mum will take away the crochet chain! It’s probably unnecessary, but as its included in the pattern I thought I’d better include it in case Baby Annabell’s head stretches the poncho.
You know I was surprised at not being overwhelmed with woolly patterns for Annabell? Well if you have the slightly, it has to be said, chipmunky looking American Girl doll then you’re in business. There are reams of pages of patterns for them on Pinterest and Ravelry. 
Back to the baby hexagons. I’ve got to figure out how to crochet half hexagons, but how difficult can it be?

Love the doll clothes you’re making. I’ve done my share of that for my granddaughters. ((hugs)), Teresa :-)
Could you knit whole hexagons then sew in place folded in half?
Or start at the longest side then decrease each end symmetrically to make the trapezium?
It’s crochet and you can’t really fold a shape in half with either crochet or knitting, the thickness of the fabric would differ,p. I don’t think it would look great.
Thanks for trying to suggest something though, I appreciate the effort.
