Non toxic nail polish for babies (identical twins)?

My friend is having identical twin girls. It was recommended that she paint the toenails of one of the girls so not to mix them up. She heard of a non toxic polish for babies. Does anyone know the product name? Thanks.Non toxic nail polish for babies (identical twins)?
One may be bigger or smaller than the other, which might help her tell the difference.





What about bracelets to tell them apart? Could be as simple as a piece of colored yarn around a wrist or ankle.





ETA:





When putting them down, always put the same one on the same side of the double stroller/crib/whatever.





Get two DIFFERENT car seats instead of identical ones. Assign each girl to her own seat. (Two different bouncy seats, etc.)





Carry a Sharpie and write their names on their diapers when you change them.....LOL!Non toxic nail polish for babies (identical twins)?
Who on earth recommended using nail polish, and is there no other way really? I mean, why not put a colored band around one baby's head or wrist?





Very strange recommendation...
Trust me she won't mix them up other people might but the mother always knows.
Painting their nails would be cute, however, babies fingernails and toenails aren't strong enough or thick enough to handle the components of nail polish. I have heard you're supposed to wait until age 2 or 3 to paint finger/toe nails.
Nail polish in general is not toxic on your nails. Other wise why would ppl wear it??? As long as she doesnt have the baby sniffing it and she does it in a well ventilated area and only on the nail......she is fine
most all nail polish are non toxic. they say if they are on the bottle. come to think of it i havent seen any that were toxic. my sister has paintedher daughters nails from day one. one is now 3 and the 2nd is 18months. i have yet to paint my daughters, she is 6 months,but is competley safe.
Look in the childrens ection and she can use the kiddie polish some types stay on very well and are always nontoxic
people have been using the polish for decades on twins with no problem.


She can make name bracletts as well until she finds a difference in them, like a colic in the hair.
