Using these Dr Martens Auburn Crib Lace - up booties is easy. Just gently slip your baby's feet into the booties and lace them up. Make sure the laces aren't too tight to ensure your baby's comfort. When it comes to maintenance, use a soft, damp cloth to wipe off any dirt or stains. Avoid using harsh chemicals as they can damage the soft Kid Lamper leather. Also, store the booties in a cool, dry place when not in use. Keep an eye on the booties as your baby grows, and replace them when they become too small. Always check the fit regularly to make sure your baby's feet are well - supported and comfortable.
