Product name: Baby Sweater Basic Spicy Mustard (blank) When you order from us, you know it's in the right place. Not just the product, but everything around it. The Baby Sweaters contain no toxins and are produced in a sustainable way in an ethically responsible factory. We do the printing ourselves, in a sustainable way, from our own store in Amsterdam. So completely locally produced! In addition, we use as little plastic as possible and ship our products in ecologically responsible packaging. Even our wrapping paper is organic. In terms of sizes, we have made it easy, because you can use the number of months that we indicate for the rompers. Of course, it is possible that a baby is just too small, too big or too plump (chubby = cute). In that case, you can use the following measurements: 0-3 months: 62 3-6 months: 68 6-9 months: 74 9-12 months: 80 12-18 months: 86
