Which Size?

An ideal time to start using a Groromper is when your baby weighs more than 21lbs 13ozs/9.9kg. Your child’s head should not be able to pass through the neck hole when the Groromper is fastened; otherwise the Groromper is too big. Remember to check the weight of your child before letting them sleep in a Groromper.

Please remember that these are recommendations only as all babies are different.

Choosing a Thickness

A number of factors determine the warmth rating of the Groromper that should be used. These include the number of clothes your baby is wearing, the temperature of their bedroom and your baby’s health. No additional bedding needed! Use your Groegg or Groegg2 to determine the temperature of the room.
