First about the additional pocket! This is a much needed piece for all moms who use their baby carriers out and about to stores or chasing older siblings around outside. Why it is not standard for all baby carriers to have a small pocket to hold mom's essential items I do not know. But I've added here to added convenience! It attaches with elastic straps around the button and is easily removed. The revolutionary Ergobaby Four Position 360 Carrier gives parents 4 comfortable and ergonomic ways to wear their babies: Back, Hip, Front Inward, and Front Outward positions.
