Press-ons for small nail beds?

Does anyone have recommendations for press ons that will fit smaller nail beds? I have somewhat small/narrow nails (plus I bite them) and I struggle to find press ons that fit my nail bed. Everything is too big and won’t adhere properly. I’ve tried children’s but they never last (I’m assuming because they make them cheap since they’re for kids). Also if you have any recommendations and how to stop biting nails that advice is welcome too :)
