I just want to sleep like a normal human being!!!

I didn't have much problem sleeping with my first baby, at least not until the last few weeks. But this time my sleep is ridiculous! The other night I was wide awake till 2 other nights I literally can't keep my eyes open past 9! I've been really tired and have taken lots of naps, but that doesn't seem to affect my nights sleep. Now after a crazy busy day yesterday I've been up since 5! Some is anxiety, or crazy dreams, but oh my word I just want to sleep!!! I have a toddler and her wears me out!
