    Fit, Fabric & Care Guide

    Great pyjamas, I came back to order more as they feel super soft and are looking comfortable too. Wash well without fading or shrinking. Definitely I buy more - Kinga B. Aug 26th

    GrowGrows are made true to size
    but a little one will get more wear out of our GrowSuits thanks to the foldover feet.

    If in doubt or between sizes, we recommend sizing up to get a full range of wear.

    You can find the size guide next to the size selector above.

    Fabric: GrowGrows are made from a super soft blend of 70% bamboo and 30% organic cotton.

    We’ve incorporated 5% elastane into the hand and foot mittens so these are still super soft but a bit more stretchy for a comfortable, snug fit. 

    Care: GrowGrows are made from natural bamboo and organic cotton fibers so should be washed with care.

    Low water temperatures and tumbled dried on a low heat, or even better air dried (they dry at room temperature in 6-12 hours).

    Please follow wash instructions for guaranteed lasting quality. For our full care guide, please see here.
