Babies can't say when they are too cold or too warm. When our daughter Michelle was born, my wife and I asked ourselves the same thing every morning: how do we dress her today? And once she was dressed, the next question came right away: is this right or wrong? We googled charts, watched TikToks and asked ChatGPT.I wanted a clear answer at a glance. So I built Button. It looks at the weather and a lot more, and every morning it shows: this is how to dress Michelle today!At first it was just for the three of us. Now Button shows every parent how to dress their baby right for the weather, so the baby doesn't get cold or overheat. The website is free for all the other little Buttons out there. The app for iPhone and iPad adds your own baby and more, like sleep and a Home Screen widget.
