Sizing Guide

To help you dress your little one according to their size, please check out our size chart below. 

We know with the ever-growing online shopping demand, customers shop from all over the world therefore we have included a global size conversion table, to make life that little bit easier when shopping with us. 

We generally cater for children aged between 0-5 years, however we do have some items that go up to age 7, and over time you will see this size range grow. 

As always, we are here to help. If you have any questions please feel free to contact us via email at contact@themummyandbabyco.com or send your query any time using the chat feature in the bottom right hand corner of the page.
