Tip: The best way to find the correct size is by body length. Weight can play a factor as well, but body length is the most important by far.

Please note that all sizes listed here are for reference only. The size labels listed here approximately correspond to measurements of your baby. They are NOT the actual clothing sizes. These measurements refer to the full body length of your baby, weight, chest circumference etc. Please refer to the diagram of the baby, which illustrate where to take measurements of your child.

If your child falls in between two different sizes, then it is best to size up to ensure a better fit. For example, if your child measures 55cm in body length, and falls between a 0-3M and 3-6M size, our recommendation is to size up and choose the larger size, which in this case is 3-6M.

Our outfits are designed for a roomier fit, suitable for both disposable and cloth diaper babies, along with lots of room to grow into, so that each piece can last longer.
