In general, doctors recommend washing newborn baby towels every two to three uses, thus the number of baby towels you need is entirely dependent on how often you bathe your little one. If your baby is still a newborn, you might not bathe them more than three times a week, therefore a baby hooded towel set including two towels is ideal for you. As the baby grows, you may want to bathe them more frequently, therefore you might need up to four towels.
