Sizing Chart

Please note that there will always be variations amongst babies in regards to age, weight & length- for example a very large newborn. The following is a general guideline for babies within the 50 (average) percentile, that should help you select the correct size for your baby (please see safety information below).

Size Age Weight Small (27") 3-11 months 10-22 lbs Medium (35") 10-24 months 22-30 lbs Large (42") 22 months-3T 28-40 lbs

We recommend a size small for children that are over ten pounds*- in the range of 10 - 22 lbs. Ideally you would wait until the baby is 8-12 weeks old (about the time they start to roll and kick off those little blankets!) The medium model can be worn once a baby reaches 22 lbs*. The large model is for toddlers that are at least 28 lbs*. *There is a certain amount of overlap that is inherent in the sizing. The goal of a good fit in a sleep sack lies more in the chest, and less in the length (all the sleep sacks are long in length and should have plenty of room for the baby to “grow into.”).
