Baby, though maybe now "toddler" is a better term, usually now can easily roll a ball and forth with you, and may be drinking from a cup (though some babies at this age still prefer their bottles). Walking may be really improving by now, but if there are still no steps don't worry - some babies can take up to 18 months to take those first steps on their own. Walking, crawling, she'll want to be on the move constantly.
Remember that children learn very well through playing, so a good variety of toys and things to play with will help their development. Not everything has to be bought from a store, either - it just needs to be safe for them and stimulating. With play, let them take charge for now as it's best they do what they're interested in at that moment. Safety is really becoming extra important because of her newfound independence, so keep everything out of reach that poses any risks, especially electricals and chemical items.
