Baby's crawling will be coming along now, and you may find you turn around, blink your eyes, and she's made it all the way to the kitchen! More bumps and scrapes are possible, and she'll be finding all sorts of trouble, so make sure you have really baby-proofed everything you can. She will also be standing, assisted, more often and for longer periods of time. Make sure she has a good variety of toys to really help her development along. If she's not quite crawling by now don't panic; every baby develops differently!
She may now be shy around strangers, where once she was so confident and bold, and could become upset if left with a babysitter or relative she doesn't know very well - this is the beginnings of separation anxiety, but in time she will learn that leaving her is only temporary and that you'll always come back.
She'll now also probably be mastering her pincer hold - picking up small objects between her thumb and first two fingers, so keep an extra special eye on her finding little pieces and items on the floor where you were oh so sure there was nothing!
