Is the pocket opening in the Sunbabies in the front or back? The one thing I do not like about the Kawaii I do have is that the opening is in the front. I'm thinking of getting some Sunbabies, but wanted to know that first! Also, does anyone know the difference in rise between Sunbabies, and any of these: BumGenius, Kawaii, Fuzzibuns, Rumparooz pockets? I find the Rumparooz is the smallest, Kawaii the biggest so where does Sunbabies fall?
