TL;DR
There's no strict rule: immigration officers sometimes ask for a birth certificate when the child's and accompanying adult's surnames differ, but enforcement is inconsistent — sometimes it's requested even with matching surnames, sometimes skipped despite different ones.
If the child has a different surname from an aunt, uncle, or other accompanying adult, it's worth carrying the birth certificate. If surnames match, it's usually not strictly necessary.
In practice, border officers sometimes do ask for proof of relationship, especially when the child and parents have different last names.
Officers may ask for the certificate for unclear reasons even without an obvious cause for doubt — better to carry it just in case.
There have been cases of inconsistent checks: a mother and child with matching surnames were asked for the original certificate, while a father and child with different surnames were waved through without questions.
