L.,
I now have a 2 year old and after going through several diaper bags, the one I have now has been my favorite. I have had it for about 6-7 months and it still looks almost new. It holds a ton of stuff, has adjustable straps, comes and the fabric is easy to clean. Mine is like a lavender color but after looking online they only have pink right now. It opens with a very wide opening since it opens like the old fashioned medical bags with a stiff edge opening. It has a outside zipper pocket and an outside velcro pocket. Inside it comes with a zipper pouch that is removable (that's where I keep my diaper and wipes so it makes changes easy) and a bunch of mesh pockets on both sides. It also comes with a waterproof zipper bag which is great for wet or dirty clothes. The best part is that it was cheap. I think it was $30 which considering how great it is, it is well worth it!! The bad part is you have to order it online. It comes from Land's End. Just go to there website and look up diaper bags. It's call the Do it All Diaper Bag. They used to offer a lot of colors, so if you don't want pink, you might want to call them and see if they will be offering others again. Good luck and let me know if you need more info.
