These beautiful, colorful nappy covers come in 2 sizes. Small is suitable for a newborn baby and up to 3 months. Large is great for 6months old plus. However, large one can have added snaps (listed as large snaps) to reduce in size and could be used as soon as 23months or even earlier. I can make amendments to order. So should you want certain color of snaps or elastic around the cover, please contact me prior purchase. For more quantities please contact me.
