I uses the Vanity Star when my son was an infant and then sold it and bought the Batignolles Horizontal a year later.
The mono canvas I wipe down with a baby wipe (alcohol free and it takes off virtually any kind of milk stain, even if it's been dried on for 3 days LOL!) and the inside you can clean out with a damp cloth.
I wish I had known about thouse purseket things, because I could have done with more pockets, but other than that, the bag holds EVERYTHING you could possibly need. And it's light as hell.
My BH is just going on a year old and it's still in mint condition.
