I just saw your post to me about the skiphop bag. I haven't carried it yet, but I absolutely love it. I love that it doesn't look super babyish and in time, I can just use it as a great tote bag for travel.
The only other issue with the skiphop bags is that they don't come with some of the basically accessories that other bags come with. They sell them separately in a bundle for $35 I think. However, I found the same bundle at TJMaxx for $15 so check there before you buy directly from SkipHop.
