Before you become a mother, your body temperature is only influenced by what temperature it actually is where you are and what clothing you are wearing. After you become a Mom, you can change your own body temperature by bundling or un-bundling your child. It's true, and it's why your mother always begs you you wear a jacket. Feel too hot? Take off that kid's sweatshirt to feel relief. Too cold? Dress him up in this cozy-looking Nordstrom Baby Quilted Velour Bunting ($38, in six colors), and you'll feel like you just sank into a warm bath. Bonus Points: It has ears! Squeeee!
