Sleeping through the night...

So, for the past week, I have been intending on making Elizabeth's 6 month doctor's appointment for her. But for some reason, I just haven't made it that far as to pick up the phone and make the darn appointment. I'm wondering if it's for one of 2 reasons...1)I hate the thought of making an appointment for my daughter to be poked with a LONG needle. Like I have said in the past, I am not sure who it hurts more, me, or Elizabeth! Or, 2) I am in denial that my daughter is already ALMOST 6 months old! Where has the time gone! It seems like just last week when I was waking up at 4am on May 12, having some pretty painful contractions! Now, the pain I have is at 3am when Miss E decides to throw me off by waking in the middle of the night wanting to play!! (Where does the pain come from that you ask??? Well, it comes from the toothpicks I have to use the next morning to keep my eyelids open at work!!) I was just telling a co-worker today that I have been spoiled when it comes to Elizabeth's sleeping schedule. Since before I even came back to work full time (at 7 weeks) she has been sleeping through the night for us. Well, I shoud say she is sleeping through the night for me, as her daddy doesn't seem to hear her when she wakes up in the middle of the night! I've decided the next time she wakes up screaming bloody murder I will just push the little button on our smoke detector to make it sound like a fire alarm is going off. If THAT doesnt wake him up...nothing will!). Anyways, I got a tad off subject there, sorry!
We were talking about Elizabeth's sleep schedule...not her dad's!
She has been going to bed a little earlier that she used to as well. She used to stay up just about as late as we did (if you consider 10:00pm late!). She would have her last feeding anywhere between 9-9:30pm and then she would soon fall into a deep sleep. I used to think that she needed that last feeding so she could make it through the night without getting hungry. Now adays though, she is going to bed as soon as 7:30pm on some nights (and still sleeping through the night!). But her average bedtime lately has been about 8:30pm. And then I wake her at 6:20am to feed her & get her ready for grandma's house. And right around 9:30am she needs to catch up on sleep again! I feel bad for waking her up every morning, and I did once consider letting her sleep until she is ready to get up (which, on weekends, when I let her sleep, she sometimes sleeps until 8:30am!), but, if I did that, I wouldnt get to see the little squirt until 4:30pm every night, and I just couldnt handle that! Spending 45 minutes every morning with Elizabeth is what gives me the energy to make it through my day, until I see her again after work. I have a morning routine that I HAVE to follow. If I am even 3 minutes behind, it throws off my day! So, on those nights when Elizabeth doesnt want to sleep, and I dont want to wake in the morning...it usually calls for a LONG day at work.
