Need nav bar at top of pages in Twenty Eleven

I’m building a web site with a Twenty Eleven child theme and have taken it out of Maintenance Mode so I can ask your help. The header image and site title was appearing on every page, which I didn’t want, so I used this bit of advice from the forums:

either doing with css:
add some of these styles to style.css:

.page-id-48 #branding { display:none; }

repeat this with the ids of each selected page.”

It worked perfectly to remove the site title and header image from each page, but it also removed the nav bar and I want to get it back so that visitors to the site can move around easily. I’m guessing this has a fairly simple solution but I’m stumped and haven’t found any help in my searches so far.
