Questions about AD825X amplifier


I am new in circuit design. In my recent design, I put a cascade of two AD825X before ADC to amplify the input analog signal. I found in the datasheet that the AD825X input bias current must have a return path to its local analog ground, I wonder if I should provide a return current path in the first amplifier if the analog signal comes a strain sensor (full-bridge), and provide another one between these two AD825X?

Thanks a lot.
