Winter Baby Museum
Step into an illustrated museum of how families have kept babies warm through history — infancy and swaddling, the prams and carriers that moved little ones through the cold, the wool and winter clothing that wrapped them up, and the cradles they slept in, each in its own gallery. Get to know the long story behind the way we bundle up a baby today.
