Who needs sleep?

Week 7 now, and we have started to transition Ella out of the rocker ("the monkey ") at night. The doctor wants her sleeping flat in a crib sooner rather than later, so we decided to give it a shot before the appointment next week. We have put the pack-and-play in our room for easier access than her crib would be in the nursery. Needless to say, Ella wants her monkey back. I want the monkey back, too. Last week, we were both sleeping for a glorious six hours almost every night.... This week, not so much. Did you know that three 2hr segments (nonconsecutive, of course, probably spread over ten hours) is not the same as sleeping for six hours uninterrupted? Very much not the same. I'm just praying that Ella gets used to the new sleeping arrangements soon; I'd like to be a functional human being again. I'm such a cranky witch when exhausted, I feel like I need to apologize to everyone around me in advance.   :(

Side note-
To be fair, Ella is not screaming all night long, but she surely is not sleeping. She has this fretful, grunting noise that wakes me up just as efficiently as crying. It's almost like she has too much room to wiggle now, even when swaddled, and she's not sure what to do with it all. In the monkey, it kept her snug and secure like a secondary swaddle and would put her right to sleep.
