Sometimes you're hot. Sometimes you're not. Sleep cycles can be instantly impacted by feeling too warm or too cool, so zip them up in a sleep sack that offers a range of warmth ratings to help your little one slumber successfully.
Good to Know: Manufacturers often provide a TOG rating which identifies the warmth of the material. The higher the rating, the warmer the sleep sack. So if your babe heats up easily, choose a product with a lower TOG rating and they won't wake up from being too warm.
