Before I had LO, I loved changing my nail color every week, and trying lots of fun and funky manicures. With a newborn, upkeep is obviously impossible, and I'm not one to pay for regular trips to the nail salon (a monthly pedicure is more than enough for me) I also would prefer to keep my nails nude, and filed short, since you never know when LO is going to need a finger to suck.

Any natural ways to whiten and strengthen nails? I would prefer nothing toxic or artificial.
