Sleep...😧

So frustrating... Almost 39 weeks pregnant and I'd love to be able to just get some sleep but that doesn't seem to be an option... Doesn't matter if I nap that day or not I can't seem to get a wink of sleep. I've tried taking the dog for long walks (as long and easy going as I can stand) and skipping the nap that day and I'm still restless all night without a wink of sleep even though I'm exhausted. I can fall asleep easier taking naps... But that obviously won't help the overnight restlessness... I'm almost at the point of knowing I have to take a nap during the day because I know as soon as night hits I won't be able to sleep! I just want to get sleep while I still can... Why is this such cruel torture...😭
