Baby won’t nap more then 30 minutes

My baby is 18 weeks old and from day one she has never been good with naps. She takes maybe 2-3 30 minute naps a day. She sleeps from 6 pm wakes at 1 for a bottle and then wakes up around 7 AM. I’ve tried swaddled, no swaddle, holding her, the bassinet, sound machine, no sound machine, making her stay away longer, and not letting her be awake for more then an hour and a half. I’m not sure what to do I feel like nothing works and by the end of the day she is so exhausted. Any tips????
