(1711–1797) seems to have been the first physician, who pleaded for complete abolition of swaddling. In his "Essay upon Nursing" of 1748 he expressed his view of contemporary child care, swaddling, the topic of too much clothing for infants and over feeding. He wrote:
Infant and toddler clothing size is typically based on age. These are usually for a baby, 0 to 3 months, 3 to 6 months, 6 to 9 months, 9 to 12 months, 12 months, 18 months, and 24 months, though there is no industry standard definition for those sizes. Most retailers provide sizing charts based on a child's , , or both, and the child's may also be used for properly sizing clothing for the infant.
