16-20°C / 61-68°F is the recommended room temperature range for your baby.

Check your baby behind the neck or on the stomach to ensure they are not too warm or cold. The Merino Kids™ Go Go Bag™ has a Tog range due to its temperature-regulating properties. A number of external factors determine the correct weight of the sleep bag (Go Go Bag™), such as the number of layers your baby has on, your baby’s health and the temperature of the bedroom. Remember to adjust the clothing underneath your sleep bag (Go Go Bag™) and the weight of the sleep bag. The requirements may vary for different children.
