You need to find the right thickness and warmth first. The Tog rating or weight of a sleep bag determines its thickness and therefore how warm it keeps your child. The higher the Tog rating (weight) the warmer the sleep bag. We are referrign to winter models as double layered and quilted bags with a warm and plush Polyester filling. Summer models are not quilted.

Please measure your little one from head to toe and match the length of your baby with the corresponding size next to it. Please do NOT buy one size up! The bag will not fit until your little one reaches the right age. The bags will start to fit once your baby reaches about 3 months old. It is generally recommended to swaddle your infant for the first 2 to 3 months or when they start ro roll.
