When to start teaching our little ones to write?

Hi, all
we all talk abt making our little one Read But What is the right time to give them a pen and help them writting or scribbling… I did this for my daughter when she was just 1yrs 9 mths old…At first she use to just scribble …but now she can write A, C, E, 1, 0 and also draws picture of apple, strawberry and Banana…
