Most diaper bags have a plastic liner in them or made of a polyester fabric blend. What you can do is use Scotch Guard and spray the backpack inside and outside

They have a few different options at Joanne fabrics. The people there are pretty helpful and will show you what they have.

Another suggestion is to include a waterproof bag for wet items. You can buy them or make them. Fabrics.com usually had a good fabric selection.

Hi Jenn. I recommend using Scotchgard Fabric and Upholstery Protector. I have not used this product myself, but it does have 5 stars from customer reviews. You can purchase it at your local home improvement store, fabric shop or even from Amazon. Good luck Jenn.

You can but a scotchgard spray which you can apply to make it more waterproof.

Hi Jenn, if you can't find Scotchgard ior Rusto-leum NeverWet, you can make an waterproof insert using a pretty shower curtain.

Hello. I am not sure I would like or recommend chemicals applied to the inside of the backpack touching baby clothing and accessories.

Babies can have very sensitive skin.

I would find a plastic zip bag perhaps something that would hold a wet bathing suit for use inside the backpack.

Academy or any sporting goods store sells a product called Camp Dry. It is a spray on to keep tents dry. I have used it on my outdoor cushions and it works great, I only spray them down every other year.
