How to use: Simply dress your newborn in the onsie, put on the beanie for a cute look and to keep their head warm, and add the booties to cover their feet. These items are great for daily wear at home or for going out. Attention: Make sure to check the fit regularly as your baby grows. Avoid using harsh chemicals when cleaning. Maintenance advice: Wash the set in cold water with mild detergent. Tumble dry on low to keep the softness and quality of the cotton. This will help the set last longer and keep it looking great for your little one.
