A bundle of joy, literally
The key to keeping your baby protected against the cold and snow is bundling him up in a snowsuit or warm jacket. Preferably get one that's water-repellant and lined with a good insulating fabric such as fleece, flannel or fiberfill. This easy-on and easy-off outer layer makes it, well, easy to get your baby quickly dressed for the outdoors and quickly undressed for the indoors. Once indoors, it's important to take off at least this outer layer to prevent your baby from sweating. Otherwise, the dampness will make your baby colder when you go back outside.
Nothing completes a winter outfit better than those accessories: boots, hats and mittens. So make sure you have all the cozy essentials, so that your little one is as snug as a bug from head-to-toe.
