To make the proper latte, steam your milk. See How to steam milk. Once your milk is steamed, pour your shot(s) of espresso into your glass. Now as you pour your steamed milk in, hold a spoon over the mouth of your steaming cup, so that any foam resting on top will be held back. Once the glass is almost full of espresso and mlik, scoop one or two large dallops of foam on top. Voila, a latte.

Now, as is mentioned above, there are different ways to do it, but this is the standard latte. Some people prefer a light layer of foam on top like themusic, others prefer to have a lot more frothed milk on top, like gm food, although I would call gm food's drink a cappucino before a latte.
