Last night Stella asked me to help her write Marni's name. I wrote "Marni" on a piece of paper, gave it to her, and forgot about it.
A little while later she called me over and showed me what she did. For the first time ever, she correctly wrote out Marni's name (or anyone's name for that matter). I wrote Stella's name on a piece of paper and a few minutes later she had correctly written it out herself.
Ok, so other boys and girls her age can easily do this. But, in our house, this was a milestone.
