I’m looking for some advice regarding our baby sleeping in a cold environment. We live on a narrow boat and in winter the nights can get pretty cold sometimes below 10 degrees. I’m looking for any advice on how we can keep our baby warm in cold conditions. I’ve read that no hat is best at night but in our scenario would it be good for our baby to wear a hat. Would it be reasonable to wrap her arms inside the blanket in a traditional swaddle and lay the baby on a sheep skin. I know the worry here is that she won’t be able to regulate her temperature at all but under the conditions what do people think?
