Baby sleep patterns suck

LT

I know they are unpredictable little things. But it is so frustrating when one night they sleep thru (8pm to 6:45am) with no one wake up, and the very next night they are up ever 1-2hrs. Ugh. And then I wonder why when she sleeps thru the night, I’m still waking every 1-2hrs. I literally cannot get a good sleep pattern for myself, even when she does sleep good.
