Olive & Emma Milestone Blankets are made from soft, cozy 100% Polyester Polar Fleece. They will photograph beautifully month after month, and only get softer with each wash! The large 40" x 60" size is perfectly designed to fit a growing baby, and is even big enough for twins! This milestone blanket includes a wreath frame prop to circle your baby's age each month, so you never forget how big your little one was at any point during their first year.
