Holding my bottle like a big girl!

Eleanor has been attempting to hold her bottle by herself for awhile now, but I think she finally has it down.  When she first start trying to hold it, she didn't quite understand that the bottle had to be tilted in order for the milk to come out.  Now she has got it down!  She continues to amaze me!  I know that every time she makes some new discovery I talk about how sad it makes me and this time is no exception.  I can't help but think that she is already, at the age of 19 WEEKS, starting to need us less.  This whole "I'm a big girl and I'll hold my own bottle" thing, although it does make it easier on mommy and daddy, is depressing!  Don't get me wrong, I want her to grow up- well eventually- but why does it have to go by so fast?  Don't even get me started on the fact that she is also sitting up now- I can only handle so much at one time!
