What size hooded towel should I buy for a newborn versus a toddler?

For longevity, many experienced parents recommend buying larger toddler-size towels (roughly 40 inches and up) rather than the smallest newborn squares. Larger organic cotton options like the KeaBabies towel are frequently cited as lasting from newborn through the toddler years, whereas compact 29–30 inch towels are best for newborn-only use or as gifts.
