If your coat is big enough you can wear your baby under your coat. You will keep each other warm. Usually all that is necessary are some booties and a hat for your baby. A scarf for your self is a nice addition, especially if you will be nursing outside. For more information on breastfeeding in the Boba Baby Wrap please visit our Nursing page. You may also wear your baby over your coat and dress your baby in a snowsuit or a full body fleece if you wish.
