I've been trying to come up with a solution to this lately because I have the same issue with my 22 month old daughter. Her grandma is always talking about painting her nails, which I so far have put off, since I'm worried about the chemicals in the nail polish. But she loves my painted toes, so I thought this might be a way to "persuade" her to let me clip her nails. I did a little searching online last week, and there is nontoxic nail polish for kids called "Piggy Paints." They even have nontoxic remover. My daughter recently started biting her thumb nails, so I think this is the only way I would be comfortable putting paint on them. The website is www.piggypaint.com, and they even have gift sets where you can pick 2 colors of paint and a bottle of remover and get free shipping. Thought you might find this interesting!
