A crocheted blanket that stays where baby needs it and won’t fall on the ground or blow away with the wind. There are openings for the car seat strap. Wish would know about this kind of blanket. When my daughter was small. I like these blanket.
The color is light purple but I have other colors also
sorry about the bear my daughter to big for this car seat now. That is real babies car seat.
