I got a few manicures with my daughter. We made it fun for Daddy to get painted nails and see if Mommy notices. The first time was serious pink. The second time was light pink with sparkles. The third time was an opaque light pink that almost matches my nails. Did she notice at all? Nope. The last 2 weeks I've done my own with an opaque light pink. Still hasn't noticed, or she is ignoring it, which I doubt.
So, it worked for me on my fingers. Toes are less noticeable. Go for it!
