Frequently asked questions
How many cotton sweaters does a baby need?
We recommend 3-5 sweaters for a seasonal wardrobe, depending on how often you do laundry. Two for daily rotation, one for dressier occasions, and one backup for spills or weather changes.
What size should I buy for a growing baby?
If your baby is between sizes, size up for a roomier fit that accommodates layers. Most sweaters have some stretch, but avoid sizes too large that might bunch or pose a safety risk.
Are cotton sweaters suitable for sensitive skin?
Yes, especially organic or unbleached cotton options. Look for GOTS-certified labels to ensure no harsh chemicals. Always wash new garments before first wear.
How do I keep the sweaters looking new after multiple washes?
Turn inside out, use cold water, and lay flat to dry. Avoid fabric softeners, which can coat fibers. A gentle cycle will preserve shape and color for longer.
