My daughter was a 25 weeker. I wish I would have made bows when she was born,she would have been all decked out
I would think a nylon headband or FOE would be the best choice. The nylon headband I would think would stretch out a little more as she grows. I would stay away from the bra strap slider just because their skin is so sensitive and she will be sleeping alot so that might dig in to her skin.
