Size Guide for Hands In & Out

* the measurements are for the sleepsuit not the baby.

Important Safety Notes:

• Our baby sleep sacks are all about the arm span - please measure your baby's arm span to get the right fit.
• Don't be tempted to get the next size up if you're hoping to get longer wear, that's not how it works.
• If too big, your baby will not get the security and snug fit that they still need in the arms. 
• More importantly, if too big there could be excess fabric that could pose a safety risk.

How To Measure Your Baby's Arm Span

• The correct way to measure your baby's arm span is to lay your baby down and measure with your baby’s arms slightly bent - this is how your baby sleeps naturally - measure from one side across to the other.
• Do not measure with your baby's arms fully stretched out - you will not get the right fit.
