The first thing to consider is what is your baby's room temperature throughout the year and then you can match it to one or a combination of Go Go Bags (Baby Sleeping Bags).
STANDARD WEIGHT
Ideal for year round use, on holidays, for both night and day sleeps. Suitable for bedroom temperatures of 18-30°C / 64-86°F (Tog: 0.5 to 1.8)
DUVET WEIGHT
Ideal for year round use, except in high summer. Adjust clothing layers to suit bedroom temperature from 15-20°C / 60-64.4°F (Tog: 1.4-2.5)
Check your baby behind the neck or on the stomach to ensure they are not too warm or cold.
A number of external factors determine the tog rating 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 their bedroom.
Remember to adjust the clothing underneath your baby's sleep bag (Go Go Bag) and the weight of the baby sleep bag. The requirements may vary for different children.
