Mom? How tall am I? Am I taller than you? Children find it very interesting to know how big they are. How nice is it to hang this growth chart on the wall and have your little one measure herself. Or if he is still too small for that, you can do it together. The advantage of black and white is that it is unisex and goes with everything. It is a white growth chart with a black arrow in the length. It is possible that the actual size differs slightly from reality, because it is really a decorative item.
