Knowing which sizes to buy on Baby Box

Sizes listed can vary slightly from product to product. Our advice is to read the product detail carefully and then (if possible) buy the next size up. Not only will buying the next size up ensure the clothing won’t be too small, but it also means the clothing will last longer!

As you will see in the above example, Baby Box have products where we sell in sizes from babies through to toddlers and also for young children. This is ideal for parents, family and friends who want to buy matching clothing for siblings where this an age gap.
