If you've already bombed you must be getting the babies coming back.  I think they make special bombs for the baby fleas.  I know this will sound crazy, but wash everything you can with PineSol.  It really keeps the bugs away.  You have to wash everything's that washable with it including your bedding.  That's how I finally got rid of the fleas in my house.
