Our sizes are expressed as the upper end of the age range for which a size is designed. As such, a size 6M is for babies between three and six months of age.
Please use a tape measure to determine the approximate measurement of your baby in Millie & Sebby clothing. In cases where a baby is in between sizes, go with the larger size.
