We've been going for nightly dog walks and lately I've been putting C in the Moby to keep him warm since it's getting pretty chilly. Right now we put him in am extra pair of socks (we don't have boots because he's only 5 months) his winter hat, a fleece coat with a hood, with a long sleeve shirt or sleeper underneath. Tonight we added mittens to the ensamble too. He seems warm enough now, but it's only getting colder.
We have a baby snowsuit for him for in the stroller, it's more Fall weight than a true puffy thing for winter, but it's still pretty heavy, too heavy for under the Moby I think.
What do you put your little ones in for baby wearing in cold weather? How much does your own body heat play into keeping them warm?
