Innovative Idea: Fitted Diaper Liner (Disposable or Cloth)

This idea is similar to the Diaper Underliner idea. It would be a liner that was like a fitted diaper, kind of like this fitted diaper shown below.

This Fitted diaper is made of fleece and I am not sure what the sewn-in insert is made of, but it is thin and quite absorbant so it may be hemp or bamboo. It has a snap closure to fit it on the baby. The diaper cover or shell goes over this, because this is not waterproof.

This fitted diaper works nice, because it can hold a regular flat liner close to the baby, which helps keep the mess pretty well contained. 

If this was a disposable fitted liner made with a material about the thickness of a paper towel, it would probably work quite well. However, it wouldn't have the same stay dry feel the fleece does, which could be done if it was a fitted cloth liner. Also, finding a way to fit the disposable liner on to a baby would need to be figured out. 

An alternative way of making a disposable fitted liner, would be to make it similar to underwear, kind of like a pull up, and then make the sides tearable so it can be torn off after use. 

How do you think this would work? Any Suggestions? 

Thank You!
