Choosing clothing for infants 0–12 months focuses on soft, breathable fabrics, proper fit, and easy dressing. Look for cotton blends, tagless seams, and adjustable closures to accommodate growth. Prioritize safe materials and non-irritating trims for delicate skin. Accessories such as hats, mittens, and sleep sacks support temperature regulation and safety for young babies. Select hypoallergenic materials, secure fastenings, and machine-washable items. Follow care labels, avoid small detachable parts, and rotate layers by weather and activity.
