DIY Car seat blankets - I worry since the part goes between the kid and seat belt it could make the straps not work as well. I would put baby in with blanket, take baby and blanket out and put baby in again. If the straps are still tight enough then it's okay. If not then I wouldn't use it.
Also known as a biscuit quilt, this DIY puff quilt is perfect for even a beginner to make and is so cute for a baby's nursery! This easy sewing project is a great baby shower gift or birthday present for a new baby and can be easily customized for a boy or girl.
