Before You Order
How to Measure
For the most accurate fit, measure your little one directly rather than guessing by age alone — babies grow at very different rates.
Chest
Wrap a soft tape measure around the fullest part of the chest, just under the arms. Keep it snug but not tight — you should be able to slide two fingers underneath.
Height / Length
Lay your baby flat on a soft surface and measure from the top of the head to the heel. For toddlers who can stand, measure heel to the top of the head against a wall.
Age & Weight
Use age as a starting point only. If your baby is between sizes, or on the taller/heavier side for their age, size up for a comfier, longer-lasting fit.
