When our baby arrived, my husband started driving more slowly. And to further protect our baby, we sought for a Baby on Board sticker. We found a 3" x 4" vinyl sticker in chrome yellow and black at Wilmar Enterprises. It was very attractive. And they were willing to install it on our car for free.
But while there, we also learned that they can customize the design. So instead of just the words Baby on Board on the sticker, we added the name of our daughter and a silhoutte of her picture. It was cool. And instead of the plain vinyl stickers, we chose the reflectorized stickers so that even at night it glows when there is another car behind us shining its head lights. Cool huh? The price of the customized stickers and the ready made stickers is the same because it is dependent on the area used. But since we chose to use reflectorized, we had to pay a little extra. But it doesn't matter because that means we still have use for the sticker even at night.
It has been 10 months ago since we installed the sticker and it is still there. It is easy to install but since they would do it for free, we asked the staff to do it. It is pretty good.
