Does anyone have a young baby who is hard to get to sleep?

Does anyone else have a young baby (3 months and younger) who is hard to get to sleep? We've been having a hard time getting her to sleep since she was 3 weeks old, now 10 weeks old. It is every nap and every bedtime. I'm starting to feel like I'm the only parent who has this problem with such a young baby! 

We swaddle, she sucks a finger because she won't take a paci, white noise, dark room, bouncing on exercise ball.
