it is! It's practically torturous! I've had RLS and insomnia issues in all of my pregnancies, so I fully expected it would happen again, it's still so difficult to get through though.
Secretly I block my kids into the living room in the morning after I've fed them breakfast, turn on the tv, and let them watch cartoons while I continue napping some more on the couch >_>
I'm sure it sounds awful, and I feel awful, but it's the only way I am managing to survive without stressing out or becoming a miserable mess. The last thing I want to do is be grumpy and awful to my kids due to lack of sleep.
I don't know either, but I'd guess they are much more experienced than I am. I've been wrong quite often, so now I either just guess for fun, or not at all.
