Without more details its hard to say exactly what the problem could be.
I don't suppose there are UDP filters between you and your parent caches?

You might want to try a configuration like this:

     cache_host sib1 sibling 8080 3130
     cache_host sib2 sibling 8080 3130
     cache_host p1 parent 8080 0 no-query default
     cache_host p2 parent 8080 0 no-query default
