I wear DD in a mei tei and put my maternity coat on over top of us both. I can do it up most of the way and we keep each other pretty snug, so I'm careful not to overdress her. I will put a hat on her if it's really chilly though. We haven't had very cold weather yet, so I'm hoping this continues to work once it starts to get even cooler.
