How do you keep your baby warm when it’s cold outside? How about putting him to bed in a Merino Kids Baby Sleep Bag? Experts say bundling your tot up in heavy blankets and layers of clothing isn’t the best bet, and caution that overdoing it can increase the risk of SIDS. A natural Merino wool sleep sack, on the other hand, is breathable, which protects your baby from overheating. And lucky for you, is giving a sleep bag away to one Inhabitots reader! The winner will receive a standard weight Merino Kids Baby or Toddler Sleep Bag in the color of their choosing. Depending on which style is chosen, this prize is worth up to $140!
