Many baby socks are sold with broad infant/toddler labels rather than a strict "12–18 months." Common size labels you’ll see are 6–12 months and 12–24 months; items labeled 12–24 months typically cover the 12–18 month range. Check each product’s listed age/size range for the best fit.
These socks are typically cotton-rich blends combined with polyester, plus small amounts of nylon or elastane/spandex for stretch. Some options use polyester microfiber for extra softness or durability.
Multipacks commonly come in six-, seven-, and nine-pair packs, so the typical range you’ll encounter is about 6–9 pairs per pack.
Designs range from vehicles and construction themes (tractors, bulldozers) to days-of-the-week patterns, as well as plush or heart-themed fuzzy slipper socks and other child-friendly motifs.
Many pairs are lightweight and marketed for year-round wear. Fuzzy slipper socks and thicker styles are intended for colder months or for layering in winter when extra warmth is needed.
