Ages are approximate because babies grow at different rates. EU sizes (62, 68, 74, 86, 92) are also height in cm. Every Wamory product page shows the approximate age next to each size.

How to measure your baby

  1. Lay your baby on a flat surface with the back straight.
  2. Measure from the top of the head to the heel with the legs gently straightened.
  3. Choose the size equal to or slightly above that height.

Example: a baby who is 63 cm tall fits size 66 better than size 59.
