Ever since I gave up caffeine years ago I usually sleep great. And I don't remember having difficulty sleeping with my first pregnancy but with this one I have so many nights where I'm so tired but I just can't fall asleep. Or I sleep for a few hours and I'm wide awake for hours in the middle of the night. I'm scared that is a sign that this baby isn't a good sleeper and I'm somehow being prepared to survive on less sleep

Anyone else have pregnancy insomnia? Did it last through your entire pregnancy? I'm tired and I just want to fall asleep!
