No, this is great! You sound better today I know with DD we had trouble at the start. A bit of a rough start, which meant she had to be retaught and I popped her on and off and coaxed her over and over to open her mouth. At first I wasn't sure that it woudl ever work - I was so disappointed to start this way - but by 3 weeks we pretty much had it.
Anyway, yes, she will learn. Hopefully very soon you won't have to think about it, she'll just go on by herself while you compose shopping lists or something more interesting.
