I thought the pnps would warp? I sure wish there were pnps that had washable pads!
Also, covering it with plastic or chucks is that safe? Idk, never did it.
I use one pnp per baby. GERBER makes waterproof pads! So does walmart (their brand). I just line the pnp with them. You can also use a quilted pnp fitted sheet for even MORE protection! I wish I had space for two cribs
