Hudson Baby Cotton & Synthetic Headbands for Newborn to 24 Months - Soft Stretchy Hair Accessories for Infants & Toddlers - Perfect for Photos, Parties & Everyday Wear

I got these for my twin daughters' baby dolls which have heads about the size of a 6 month old. I haven't tried them on a real baby's head but they go on (and stay on) the dolls' plastic heads very well. They are pretty stretchy and comfortable and don't seem like they'd be the kind that digs into the baby's head and leaves marks like other ones I've seen. If I had a baby girl, I would definitely use these for her since they are so adorable, trendy and comfortable looking. As far as size range, I think they would probably be a bit too big for a newborn, but might work for a 1 month old and fit comfortably up to about 24 months(I tried it on my 32 month old son who is a little smaller than average and it seemed to fit well). Also, in case you are wondering, they are not the kind that unties all the way into a sash. They do, however, untie in a way so you can adjust the size of the bow(see pics).
