Using this baby crawling suit is a breeze. Simply dress your little one in it, and let them start crawling around the house. As they move, the suit will clean the floor. When it comes to choosing a size, always check the size chart and consider your baby's height and weight. For maintenance, you can machine - wash or hand - wash the suit. Just use a gentle cycle and mild detergent to keep the cotton in good condition. Also, make sure to check the suit regularly for any signs of wear and tear to ensure your baby's safety.
