It is so hard to see when you're in it - even with more than enough Labrador experience to help out.
It's a good idea to keep popping her into her crate - it'll teach her where to go and as you say, give her a fighting chance to have a good sleep. Puppies are so much like toddlers - some would say even harder to manage!
I thought she sounded bright - with masses of promise, especially if she's picking things up so quickly. She will be a dream to train as long as you crack what makes her tick.
I expect it's attention that rings her bells at the moment - both positive and negative.
Your question about bonding is an interesting one, and it took a while for me in particular to bond with daisydog3. She didn't actually know that it was comforting to be with people - the complete opposite to daisydogs1,2 and 4 (all 4 are Labradors who I work).
Once she'd worked out the comfort thing was good - and that she wanted to be with us more than most things (except for birdies and badger poo) she went too far the opposite way. Even at 2 she still likes to lie on my feet while I'm cooking in the teeny gap between my feet and the kitchen plinth. She used to fling herself at us for cuddles no matter what we were doing, she still likes to lie around the back of our necks a bit like a scarf when we sit on the sofa. She also likes to press herself into any bit of us she can reach as hard as she can for a cuddle.
I particularly remember she was awful about being dried. Biting, blood curdling growling just awful. On the face of it she sounded like an absolute savage. Actually, she was overwhelmed and frightened and instinct took over. It took a while, but we jollied her out of it. Lots of high, sing song 'silly, silly billy - It's only a towel, silly, girlie' doesn't matter what, actually as long as it made her think it was an OK thing to be happening. Telling her off would have been the absolute worst thing to do. She love, love, loves towelling off now!
She worked out the bonding thing for herself. I didn't want to make any special effort because of her tendency to go completely manic with stimulation - and because we have 3 other dogs. I don't think it is a good idea to make any special effort with one over the others - and I don't think it can be taught, as such. They have to work it out.
What built the bond with her was training. One on one - especially with a bright dog. It's more important than you can imagine to take them out one at a time. Firstly and most importantly, because you really don't want them building up a stronger bond with each other than they have with you, but also because it creates such a strong bond with you.
Some time spent one on one training each day - no more than 5 minute sessions - will really help.
You'll also have to teach her how to ask for attention if she's anything like mine. Mine tried all sorts of capers - some of which bloody hurt until we worked out that she had missed a vital part of socialisation and didn't have any idea what to do.
It mignt also help to bear in mind just how much she is having to learn and cope with, compared to your average, home reared pup. She will be coming on in leaps and bounds, even if it is in things she really ought to know about by now! Treat her like a toddler and you won't go far wrong!
