I love all of the features/fabrics on the Mixx, but I'm worried about the size of the child seat. My baby isn't here yet, so I don't know how big he/she will be, but the seat seems a little small. Has anyone had any issues with their baby outgrowing this stroller too quickly? The Tavo seems like the seat is much larger the the Mixx, but I don't like the fact that it can't be turned around to face me. Any comments from mommies who have the Mixx or Tavo are appreciated!
