That 12pm feeding I mentioned for my girls... I get up to feed them! It really stinks when I have finally just gotten to sleep good then the alarm goes off for me to feed them. In the 'early days', I used to also get up again maybe two/three hours later to test Mia. Thank goodness we got to a point where that is not usually necessary.
On top of that, Willow needs loving every night at some point.. usually in the 3-4am range.. sometimes she needs it at some other point during the night, too. Sometimes it can last just a few minutes and other times it goes on for what seems like forever. She gets on top of me, or at least with the front half of her, and kneads me while I pet her over and over and over. If I stop because I have started to dose off, she takes her paw and touches my cheek to get me to start again. (Which is much better than peeing on me..HAHA.)
I have not had a full nights sleep since Mia's diagnosis.
Like I said, little brats!
