They don't have a "baby" size so I took the small size & reduced it from 100% to 85% & made the elastic 6 1/2" long instead of 8 1/2" long. Hope you can find a charity that will accept them.
Even without a printer you can click on the "face mask sewing pattern" & hold a piece of paper up to your monitor & trace around the pattern pieces with a pencil to get you a template to use.
