If you are carrying a baby close to your body in a wrap or sling, it provides protection from the wind and the baby carrier almost constitutes an extra "layer" of clothing. It is therefore preferable to dress baby in a bodysuit or T-shirt made of a lightweight and breathable material. Take care to cover as much of the body as possible (arms, legs, top of the feet, etc.) in order to protect from the sunshine; not to mention the essentials: hat and sunglasses!
