So I was going to make my second muslin just a straight 12-18 month size with added length. But then I remembered the issue about the yoke being snug over the head. The 3T yoke fit over my daughter's small head, but it wouldn't have, were it much smaller. Is there any fix for this? I'm about ready to give up on the idea of a Christmas Playdate, but I really don't want to :(
