Baby grows so fast, that is why it's important to record their growth. The number on the towel represents "month", it will help show how old the baby is on photo/video. For delicate baby skin, our number one recommendation is the incredibly soft gauze material. Normal towels can be slightly too rough. With gauze towels, there's no need to worry. These towels are perfect to dry and wrap your baby in after bathtime. Even letting them hold on to the towel during the bath can be incredibly comforting. These towels are thin and lightweight yet effective, fast-drying and perfect for easy travel or going out.
