Subject: Does taking Anti-biotics impede a child's immune system in any way?

Two people at work said they don't like to give their kids anti-biotics because 
their want the kids to develop their immune system. By the time you feel sick 
from a bacterial infection,is not your body already fighting the infection thus 
developing an immune responce for the future to that bacteria? Would it not be 
a mute point to the immune system in the case of a virus? It would build an 
immune response to the virus even with the anti-biotics?
