Rory's still not sleeping

Well, we had a wonderful eating week last week, but unfortunately Rory stopped sleeping through the night. She is back to her crappy eating, just picking here and there....but she's still not sleeping. I have been feeding her at night again, because it's the only way to get her to stop screaming. Unfortunately, it is only a short fix before she is up and crying again. Last night I fed her at 11pm and 3 am, she only drank 2 oz each time. I'm fearful it is a vicious cycle. Like, she's not eating again because she's eating more at night, but she's eating more at night because she needs comfort from an upset tummy....OR she's being a little shit and is crying because she KNOWS I'll come to her. I just can't figure it out. She is definitely testing my patience lately. I think it is more frustrating to have her eat for a week and then stop than for her to just NOT eat. AND, I'm afraid that since I veered off course with what the clinic wants me to do, that when we go back in on Aug 5th, Rory will be confused. Obviously, the distraction of the tv was only a temporary novelty for her, because it's no longer working. I have to crack the whip on myself and get back on track. I'm just so sad. I hate that I am inconsistent, I want to be consistent, but honestly, I'm tired. Tired of not seeing consistent results. Tired of not sleeping. Tired of feeling guilty because it's too damn hot to walk anywhere with her. Tired of wasting away our mornings just to get to naptime. I swear, if she wasn't so damn cute I'd trade her in. lol. Naw, I'm keeping her I guess. How could I not? Look at how sweet she is!
