I wore D but didn't get started till he was older and the weather was warmer. I want to start wearing A now to go shopping and stuff, but I'm not sure how to do this in cold weather. Do I put her in the carrier at the car, exposing her (and me) to the cold for a bit and then just wrap my jacket or a blanket around her? Do I carry her in to the store and then put her in to the carrier? Do I put her over my coat, take my coat off first, not wear a coat at all? This probably shouldn't be this complicated, but I'm sleep-deprived and my brain is functioning at like 1/3 its normal capacity.
