I resolved the matter this way:

The New Covenant is new with respect to Moses, but not new at all with respect to Abraham.

It is the covenant with Abraham that we inherit as children of Abraham's faith (not necessarily Abraham's genes). The "Old Covenant" is Moses, not Abraham. That covenant came 430 years after Abraham and did not cancel or replace the original.

For me the burden of proof is on credobaptists that children were "kicked out of the covenant" until they articulate faith in an adult manner.
