Wellll, I should say that there doesn't appear to be an insulated bottle compartment, although there is a bottle compartment. It seems like the right size overall, and I'm guessing, as a first time mom, that the inside layout is good. It came with a matching changing pad, but I don't think we'll be using it because it's one layer of fabric and looks mighty uncomfortable. It feels like durable/waterproofy canvas. I'm happy about that because it was this or one of the 100% cotton ones off etsy, and this seems much more durable.
