Welcome to the Cushii size guide. We know that finding the perfect fit for your little one is important for their comfort and your peace of mind. Our garments are designed to be comfortable and allow for growth. Please use the charts below to find the most suitable size. If your baby is between sizes, we recommend sizing up.

How to Measure

Diaper: Use a soft measuring tape and ensure it is snug, but not tight.

  • Chest: Measure under your baby's arms, across the fullest part of their chest.

  • Waist: Measure around your baby's natural waistline, just above the belly button.

  • Hips: Measure around the fullest part of your baby's bottom and upper thighs.

  • Length/Height: For total length, measure from the top of the head to the bottom of the heel while your baby is lying flat.

Please see the below size/age chart is a guide and if unsure we recommend sizing up.
